车辆轮胎动力学仿真模型分析

摘要

The paper describes the characteristics and using range of some common tire models,and introduce tire testing which is a parameters visualizer tool in ADAMS/CAR. Relying on this tool, the paper compared one kind of Physical tire model and one kind of Empirical and Semi-empirical tire model. Based on one kind of magic formula tire model, we verified that the relationship between lateral forces and longitudinal slip ratio, aligning torque and longitudinal forces,longitudinal force and vertical slip rate.%分析了各种常用轮胎模型的特点和利用范围，介绍了ADAMS中轮胎试验台（tire testing）这一轮胎参数可视化工具，利用这一工具分析比较一种物理轮胎模型与一种经验-半经验轮胎模型间关于侧向力与纵向力、纵向力与纵向滑移率、回正力矩与纵向滑移率的力学特性，针对一种魔术公式轮胎模型验证了侧向力和纵向滑移率、纵向力和纵向滑移率在不同载荷下的力学关系特性。
