静态加载侧翻稳定性试验仿真评价研究

Simulation Evaluation Research of Automobile static loading test roll tumbling stability

文章从汽车稳态侧倾的过程中,推导出关于汽车最大侧倾角和汽车参数之间的理论关系式为汽车在设计时提供一定的理论依据。文章对车辆在静态侧倾过程中在不同车辆状态进行分析,得到在不同状态下的仿真结果,通过与实际试验结果进行比对分析,在考虑轮胎和悬架的刚度更为接近实际的试验的结果,认为该方案比较理想。

In this paper, the theoretical relationship between the vehicle＇s maximum inclination angle and the vehicle＇s parameters is deduced from the vehicle＇s steady lateral lean process. In this paper, the simulation results of different vehicle States are analyzed in the course of static lateral tilting. By comparing with the actual test results, the stiffness of tire and suspension is closer to the actual test results.
