基于LuGre摩擦理论的动态轮胎模型研究
Research of Dynamic Tire Model Based on LuGre Friction Theory
摘要
Abstract
Based on the dynamic friction theory,the dynamic tire LuGre model which could be used to study the vehicle dynamic characteristics was set up,and the expressions to describe the vehicle tire longitudinal and lateral forces were established,as a basis for vehicle dynamics simulation.This paper used the genetic algorithm as a tool to identify the model in the static parameters,and then going the parameter identification of dynamic model,and it analyzed the influence of model parameters on the model accuracy.Seven degrees of freedom vehicle dynamics model is set up in the Matlab/Simulink,including the vehicle longitudinal motion,lateral movement and yawing motion and dynamic characteristics of the four wheel rotation.The results show that the accuracy of the established dynamic tire model is good,and it can be used in vehicle dynamic characteristics simulation research.关键词
