A Study on the Mechanical Properties of Tire in the High-Speed Frontal Impact Condition

Abstract

The simulation accuracy of the tire model has an important effect on ensuring the simulation accuracy of the vehicle model in vehicle frontal crash simulation. A tire sub-model is set up based on the data of a Changan vehicle tire, and dynamic impact analysis for the tire is performed with a certain velocity. Tires’ acceleration, speed, and deformation parameters of mechanical properties are acquired and compared with the tire impact test data. Then, the tire finite element model is optimized through comparing the tire performance parameters with the test results. After that, it is applied to the simulation model of high-speed frontal crash condition to analyze the effect of tire simulation method on the consequences. Comparative analysis is performed between simulation and test. The results show that the vehicle acceleration and tire deformation in the vehicle crash model are more consistent with the test after optimization of the tire model, thus improved the simulation precision of tire model in simulation analysis.
