Abstract

In many crashworthiness applications the tire and suspension play a significant role in the behavior of the vehicle during the crash. For many of those applications, that role can be effectively modeled with simplified models of those parts. However, in some crash events the tire and suspension need to be modeled in great detail in order to accurately capture the response of the vehicle. To better simulate such events, a new tire model was developed that takes into account the major components of a tire, including the tread, sidewall, steel beads, steel belts and body plies. Laboratory testing was performed in order to help validate the tire model. LS-DYNA, a nonlinear finite element analysis code, was used as the simulation tool. Some important details about properly pressurizing the tire and using relative damping to control excessive tread vibrations were discovered during the research. A significant effort was made to keep the number of elements in the model as low as possible without sacrificing accuracy in order to keep computational costs down. The new tire model was used on several applications including impacting a curb, driving over rocks, and landing on a culvert grate to demonstrate its effectiveness.
