Analysis on Sport All-Terrain Vehicle Jumping with Multibody Dynamic Simulations 2005-32-0013

In case of all-terrain vehicles (ATVs), which have characteristics of both motorcycles and cars, the effect of the rider movement can not be ignored when analyzing ATVs' behavior. We have developed a simulation system of an ATV with rider operations, which are throttle control and rider movement, by using multibody dynamic simulation software. To quantify the rider operations and verify the validity of the simulation system, we have conducted experiments and simulations on a sport-ATV in two jumping patterns. In this paper the results of comparison between simulation and experiment are reviewed. Then, we report the analysis results of the effects of the rider operations and the ground profile to ATV jumping behavior with using the simulation system.
