Chandrashekhar Thorbole, Director of Thorbole Simulation Technologies presented this at CPSC's ATV Safety Summit Oct. 12, 2012. ATV crashes involving rollovers are mainly governed by factors such as an ATV’s dynamic characteristics, terrain properties, and rider performance. To develop successful safety strategies, ATV crash reconstruction requires detailed crash site surveys and proper understanding of injuries involved, which is often time consuming and costly. Computer simulation technology, widely used in various engineering fields to improve occupant protection features, could be applied to the field of ATV safety. The requirements of an accurate dynamic ATV model, ATD (Anthropomorphic Test Device) models, and terrain environment are essential for any successful ATV crash simulation. In order to successfully conduct sensitivity analysis to understand the most significant factors dictating injury outcomes the ATD must possess bio-fidelity of a bicycle or motorcycle rider, the ability to grip a handle bar, and have a human face profile in order to facilitate correct helmet fit. The Arkansas ATV Safety Research group has developed a computer model of an ATV which can be used to simulate crashes. Future injury simulations will be conducted utilizing a rider and passenger. Pending activities also involve the development of a child rider ATD model for child injury prevention education and the development of applications for testing ATV helmets.
