There is lot of upgrade in the technology of the automobile these days. Competition on the speed of vehicles going on in the market. But also this speed leads to accidents if vehicle don’t stop on time. Disc brakes in the vehicles give much better performance compare to drum to stop the vehicle also the heat generated during braking force can be easily dissipated as disc brakes are open to atmosphere. But the main problem is with the material used in the disc brakes in some vehicle. Manufacturers use disc of steel which have short life span and the weight is bulky near the tire.

The heat generated due to friction during braking operation causes several important negative effects on the brake system. It is then important to determine the temperature field of the brake disc. In the present work, a transient thermo-mechanical finite element analysis (FEA) is performed to determine the braking efficiency of a Carbon Ceramic disk brake and compared to a Glass Fiber (S-2) brakes. The aim of the work is to investigate the rise of the temperature of the disk brake under severe braking conditions and the stresses generated from it. The investigation will be done using ANSYS software. ANSYS is a powerful FE package used to determine stress, strain and heat transfer in complicated problems

Safety aspect in automotive engineering has been considered as a number one priority in development of new vehicle. Each single system has been studied and developed in order to meet safety requirement. Instead of having good suspension systems, Air bags, good handling and safe cornering, there is one most critical system in the vehicle which is brake systems. Without brake system in the vehicle will put a passenger in unsafe position. Therefore, it is must for all vehicles to have proper brake system. For the purpose of safety and increased life cycle of the disc brakes this paper deals with the design modification of a disc break so as to produce better thermal and structural performance.

In these paper structural fields of the solid disc brake during short and emergency braking with four different materials is studied. The distribution of the tempe rature depends on the various factors such as frict ion,surface roughness and speed. The effect of the angular velo city and the contact pressure induces the temperatu re rise of disc brake. The finite element simulation for three -dimensional model was preferred due to the heat fl ux ratio constantly distributed in circumferential direction . Here value of temperature,friction contact power,nodal displacement and deformation for different pressure condition using analysis software with four materi als namely cast iron,cast steel,aluminium and carbon fibre reinforced plastic are taken. Presently the D isc brakes are made up of cast iron and cast steel. With the v alue of simulation result best suitable material fo r the brake drum with higher life span is determined.

Disk brakes are using from so many years in automotive and still researches are going on in this field for decreasing the temperature effect so that by this we can operate easily. Many new materials are introduced for the disk brake rotor to withstand high temperature produced during braking action. Apart from the high temperature property, the disc rotor materials must also have high thermal conductivity property, as this property decides the amount of heat dissipation to the air stream from the disk rotor. A brake material with good temperature and high thermal conductivity property gives maximum efficiency by overcoming the problem of thermo-mechanical instability [TEI] in the rotor which is more common in low thermal conductivity brake rotor material. In the present work, a Grey cast iron material and metal-ceramic has been chosen for the disk brake rotor. Number of methods before already introduced to know the history of the different materials related to disk brakes, analysis will be done in 2d and 3d in analytical and numerical methods. With different types of assumptions these numerical methods ranges from finite differences to finite elements. To conclude the temperature history for the Grey cast iron material, and metal-ceramic, a numerical simulation technique called finite element method is used. Transient analysis is carried out in ANSYS to predict temperature distribution as a function of time in the disk brake rotor. The results from the transient analysis are compared. As the brake rotor can be treated as the coupled field problem, it is mandatory to do structural analysis after performing thermal analysis in ANSYS to study the stability and rigidity behavior of the rotor material. The results from the transient analysis are given as the input to the structural analysis in order to conclude the stress distribution and displacement in disk brake rotor under thermal loading. The stability behavior of different brake rotor material is compared to facilitate the conceptual design of the disk brake system.

Coupled structual thermal analysis of disc brake
Coupled structual thermal analysis of disc brake
eSAT Publishing House
Braking system represents one of the most fundamental safety critical components in modern vehicles. Brake absorbs kinetic energy of the rotating parts (Wheels) and the energy is dissipated in the form of heat energy to the surrounding atmosphere. It decelerates or stops the vehicle. When brake is applied to the disc brake it is subjected to high stress, thus it may suffer structural and wear issues. Hence for the better performance, structural, stress and the thermal analysis is preferred to choose low stress material.

Automobile braking system is one of the most important mechanical devices among the others. The disc brake is a device that slows or stops the rotation of a wheel by converting the friction to heat. But if the brakes get too hot, they will cease to work as they cannot dissipate enough heat. This condition of failure is known as brake fade. Disc brakes are exposed to large thermal stresses during routine braking and extraordinary thermal stresses during hard braking. Ventilation applications on disc brake can significantly improve the brake system performance by reducing the heating of the discs. In this study, the thermal behavior as well as the performance of ventilated brake discs using different pattern of holes will be investigated at continuous brake conditions with finite element analysis and the results will be compared with a solid disc.

This paper deals with the pressure due to expanding combustion gases in the combustion chamber space at the top of the cylinder which generate thermal stresses due to presence of heat involved on the reciprocating masses. The present work deals with the use of different materials for IC engine piston and a comparative study is made to achieve the best possible result. Piston parameters are taken using the conventional formulas and are constant throughout the analysis. Moreover the boundary conditions are chosen such that the piston does not moves sideways except in the direction of line of action of the piston itself.

During engagement of clutches when vehicle is started or during engagement of clutch when vehicle is in motion, the friction clutch generates chatter or also called as Judder vibrations. The vibrational behaviour of friction clutches not only affects the dynamics of transmission system but also the vehicle as result of excitation transfer to body via suspensions and mountings. If excitation level is high then it may cause discomfort to passengers. In addition to those effects vibrations generated may cause wear of friction material and thereby reducing performance and life of clutches.

In the internal combustion engine there are many reciprocating parts which are responsible for giving the motion to the engine. from them the piston is very important part of the internal combustion engine.. The working condition of the piston is so worst in comparison of other parts of the internal combustion engine. There is very high probability to failure of the piston due to high wear and tear. So there is necessary to inspection the working condition of piston. In before there is no availability of software packages. So there is difficult to check out the failure of the piston, it is also very time taken process. In now days the software packages are used to consume less time and give quality assurance. In this study work there are two steps of analysis of the piston they are Designing and Analysis. Firstly design the model of the piston in giving design specification on the modelling software like INVENTOR . Then giving it the constraints which are act on the working condition of the piston after import the model of the piston into the analysis software ANSYS in IGES format. Then the analysis become completed on the different parameters(temperature, stress, deformation) and easily analysis the result. In this work the piston become optimized after the reducing the material of the piston. the mass and volume of the piston become reduced. The deformation also increased after the optimization which is responsible for the stress distribution on the piston head or piston crown.

In this paper three different cut patterns of brake disc are studied for heat transfer rate. Heat transfer rate increases with number of cuts in the disc. This is because large area is exposed to air which makes more heat transfer through conduction and convection. But increase in number and size of cuts decreases the strength of disc. And analysed thermally in ANSYS for different material and design created in CREO 3.0.

Since ages gender difference is always a debatable theme whether caused by nature, evolution or environment. The birth of a transgender is dreadful not only for the child but also for their parents. The pain of living in the wrong physique and treated as second class victimized citizen is outrageous and fully harboured with vicious baseless negative scruples. For so long, social exclusion had perpetuated inequality and deprivation experiencing ingrained malign stigma and besieged victims of crime or violence across their life spans. They are pushed into the murky way of life with a source of eternal disgust, bereft sexual potency and perennial fear. Although they are highly visible but very little is known about them. The common public needs to comprehend the ravaged arrogance on these insensitive souls and assist in integrating them into the mainstream by offering equal opportunity, treat with humanity and respect their dignity. Entrepreneurship in the current age is endorsing the gender fairness movement. Unstable careers and economic inadequacy had inclined one of the gender variant people called Transgender to become entrepreneurs. These tiny budding entrepreneurs resulted in economic transition by means of employment, free from the clutches of stereotype jobs, raised standard of living and handful of financial empowerment. Besides all these inhibitions, they were able to witness a platform for skill set development that ignited them to enter into entrepreneurial domain. This paper epitomizes skill sets involved in trans-entrepreneurs of Thoothukudi Municipal Corporation of Tamil Nadu State and is a groundbreaking determination to sightsee various skills incorporated and the impact on entrepreneurship.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.

Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.

Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

ENGINE PISTON AND PISTON-RING USING CATIA AND ANSYS SOFTWARE Isam Jasim Jaber and Ajeet Kumar Rai* State Company for the Agricultural Supplies, Ministry of Agriculture, Republic of Iraq. *Mechanical Engineering Department, SSET, SHIATS-DU Allahabad ABSTRACT In this present work a piston and piston ring are designed for a single cylinder four stroke petrol engine using CATIA V5R20 software. Complete design is imported to ANSYS 14.5 software then analysis is performed. Three different materials have been selected for structural and thermal analysis of piston. For piston ring two different materials are selected and structural and thermal analysis is performed using ANSYS 14.5 software. Results are shown and a comparison is made to find the most suited design. Key words: Piston, Piston-Ring, CATIA, ANSYS. INTRODUCTION The modern trend is to develop IC Engine of increased power capacity. One of the design criteria is the endeavor to reduce the structures weight and thus to reduce fuel consumption. This has been made possible by improved engine design. These improvements include increased use of lightweight materials, such as advanced ultra-high tensile strength steels, aluminum and magnesium alloys, polymers, and carbon-fiber reinforced composite materials9. The integration of lighter weight materials is especially important if more complex parts can be manufactured as a single unit. In the next 10–20 years, an additional 20–40% reduction in overall weight, without sacrificing safety, seems to be possible. Cuddy et al (1997) have reported that for every 10% weight reduction of the vehicle, an improvement in fuel consumption of 6–8% is expected. Improved engine design requires optimized engine components. Therefore sophisticated tools are needed to analyze engine components. Engine piston is one of the most analyzed components among all automotive or other industry field components. The engine can be called the heart of a automobile and the piston may be considered the most important part of an engine. Many sophisticated Aluminum piston analysis 64

Mechanical Engineering and Technology (IJMET), ISSN 0976 – 6340(Print), ISSN 0976 – 6359(Online), Volume 5, Issue 2, February (2014), pp. 64-73, © IAEME methods have been reported in the past years. Silva 2006 has analyzed fatigue damaged piston. Damages initiated at the crown, ring grooves, pin holes and skirt are assessed. An analysis of both thermal fatigue and mechanical fatigue damages is presented and analyzed in this work. A linear static stress analysis, using ‘‘cosmos works’’, is used to determine the stress distribution during the combustion. Stresses at the piston crown and pin holes, as well as stresses at the grooves and skirt as a function of land clearances are also presented. Buyukkaya et al (2007) has investigated a conventional (uncoated) diesel piston, made of aluminum silicon alloy and steel. He has performed thermal analyses on pistons, coated with MgO–ZrO2 material by means of using a commercial code, namely ANSYS. Finally, the results of four different pistons are compared with each other. The effects of coatings on the thermal behaviors of the pistons are investigated. It has been shown that the maximum surface temperature of the coated piston with material which has low thermal conductivity is improved approximately 48% for the AlSi alloy and 35% for the steel. Saad et al. ( 2008) has done numerical analysis to analyze the stresses due to thermal cycle with different aluminum alloy of piston .Finite element method was used to evaluate the coupling field (thermal –stress) on the piston. ANSYS5.4 Finite element code is used to carry out the modeling process to determine the coupling stress .Two models with three dimensions are created .The first is used to evaluate the temperature distribution through the piston volume, and the second is used to evaluate the thermal stress distribution due to heat gradient and different materials. The result show the maximum range of temperatures is 4.3 °C and increases with decreasing of material thermal conductivity .Thermal stress is concentrated on the piston edges and depends on the material types. Gudimetal et al. ( 2009) has reported a CAD model of a damaged internal combustion (IC) engine piston and then has used the state-of-the-art ANSYS finite element analysis package to perform a linear static and a coupled thermal-structural analysis of the component. Further, a parametric evaluation of the material properties vis-à-vis operating conditions is carried out to generate a relational database for the piston to arrive at optimal design solutions under different operating conditions. Wang et al. (2010) has reported a solid model including piston and piston pin of a new designed piston by Pro/E software, and the finite element analysis model was also established by using ANSYS software. The thermomechanical coupling stress distribution and the deformation were firstly calculated. Considering the nonlinear material properties of piston and piston pin, the Newton-Raphson equilibrium iterative method is applied. Calculating results indicates that the maximum stress concentration is at the upper end of piston pin boss inner hole, and is mainly caused by the peak pressure of the fuel gas. Zeng et al. (2010) has setup a geometry model of a diesel engines piston in UG graphics. The temperature fields of the piston for burning diesel and DME separately are calculated using ANSYS 10.0. The result shows that the variation of the thermal load by substituting diesel with DME is still within the thermal strength of the material. The temperature of the DME fueled diesel engine decreases along the piston axis from top to bottom. The temperature of the piston of DME fueled engine increase as a whole comparing with burning diesel. However, the temperature field distribution has no significant change decreases and then increases from the combustion chamber center to the edge, and decreases again to the edge of the piston top. Durat. et al (2012) a steady-state thermal analysis was performed to evaluate the temperature gradients in the standard and two different partially stabilized ceramic coated pistons by using Abaqus© finite element (FE) software. A sharp increase in the temperature of the coated area of the piston was observed as a result of FE simulations. It is concluded that the annulus Y-PSZ coating may contribute better, as compared to Mg-PSZ, to decrease the cold start and steady state HC emissions without auto ignition, since the temperature in the area shows a local sharp increase. Junju et al. ( 2012) has tried to reduce the intensity of thermal and structural stresses by using the ceramic material Silicon Nitride as the material for piston crown (the top portion of the piston).As the crown material is brittle in nature and skirt material is ductile in nature. A ceramic reinforced fiber strip was introduced in between ceramic crown and Al alloy skirt 65

In this work Eutectic Al Alloy (Si 11-13%) was taken as piston material. Initially thermal and structural analysis was performed on Al Alloy piston without silicon nitride crown and then with silicon nitride crown using the software ANSYS. Then the results obtained are compared. The comparison of results indicated that the piston which is arranged by silicon nitride crown is better to withstand high thermal and structural stresses than the piston which is not arranged by silicon nitride crown. The present work has been undertaken with the following objective. 1- To design an IC engine (piston and piston ring) by using CATIA V5 R20 software 2- To perform the structural and thermal analysis (of piston and piston ring) using ANSYS 14.5 software.

As it is expected maximum displacement is observed at the top of the centre of the piston. It is shown in the figure 8, 10 & 12 that the maximum stress intensity is observed in AlSl 4340 with 3011.903 MPa and minimum in Al alloy 4032 with 295.69 MPa. It is observed that the maximum stress intensity is on the bottom surface of the all piston crown and along the edges. Again in piston made of titanium alloy moderate stress intensity is found. Whereas the yield strength of the piston is very high in Titanium alloy piston followed by AISI4340 steel and Al alloy 4032. Thermal analysis of piston shows that the value of maximum temperature is same for all the materials at the top surface of the piston crown, but minimum value of temperature in the piston made of titanium alloy. The highest value of minimum temperature is found in the piston of Al alloy. This is due to thermal conductivity of the materials. Minimum temperature is in the skirt of the piston is observed as shown in figure 13, 15 & 17. Figure 14, 16 & 18 shows that max total heat flux is observed in piston of Al alloy and piston of titanium alloy shows the lowest value of max total heat flux along the edges. Piston rings are made of Nodular Spheroidal Cast Iron & Grey Cast Iron. GCI Piston Rings show more deformation than in NSCI. Stress intensity is equal in both. Maximum temperature is equal in both materials, where minimum temperature is higher in GCI, which is 222.8oC. Here, maximum total heat flux is observed in GCI piston rings & minimum value in NSCI piston rings. CONCLUSION It is concluded from the above study that using CATIAV5R20 software design and modeling become easier. Only few steps are needed to make drawing in three dimensions. Same can be imported to ANSYS for analysis. Piston made of three different materials Al alloy 4032, AISI 4340 Alloy steel and Titanium Ti-6Al-4V (Grade 5) are analyzed. Their structural analysis shows that the maximum stress intensity is on the bottom surface of the piston crown in all the materials, but stress intensity is close to the yield strength of Al alloy piston. Maximum temperature is found at the centre of the top surface of the piston crown. This is equal for all materials. Depending on the thermal conductivity of the materials, heat transfer rate is found maximum in Al alloy piston and minimum in 72
