摘要:介绍了四种常见的车辆操纵稳定性仿真用轮胎模型,即简单非线性轮胎模型、半经验公式轮胎模型、魔术公式轮胎模型和分析轮胎模型。通过对含上述四种轮胎模型的车辆动力学系统进行C级不平路面上转向盘角阶跃输入仿真试验,结果表明车辆系统响应总体趋势一致。以简单非线性轮胎模型为例,对比了车辆在水平路面与正弦路面上的响应,分析了不平路面的频率和幅值及车速对车辆操稳性的影响。

Abstract:Four common tire models for simulation on vehicle handling and stability were introduced, such as simple nonlinear tire model, semi-empirical formula tire model, magic formula tire model and calspan tire model. By steering wheel angle step input test on the C grade road, the comparative effect of different tire models to the vehicle key performance indicators can be included that the overall response of the four types of tire model is consistent. After that, chosen the simple nonlinear tire model, the contrastive analysis of vehicle model between on the smooth road with on the sinusoidal road was done. And the effect of road frequency, amplitude and the speed to the vehicle handling stability were also analyzed.
