ABSTRACT

For vehicle dynamics simulations, tire models are lacking that can accurately predict spindle loads resulting from durability road events, such as curb impact or chuckhole impact, and for off-road scenarios. In this paper, an efficient three-dimensional tire model is presented for use in simulating such events. The model is based upon a precomputed table that characterizes the force-deflection behavior of the tire sidewall, which is coupled to standard shell elements to model the tire tread. Comparisons are given between computed and experimental results for several different loading cases that demonstrate the effectiveness of the proposed model
