摘要
基于Pacejka轮胎模型,建立了包括纵向运动的三自由度四轮转向侧向动力学非线性模型.通过单移线、双移线以及蛇行试验与仿真,结果表明,对应变量的测量值与仿真值在时域范围内变化趋势一致且吻合程度较高.这表明所建立的非线性侧向动力学模型对试验样车侧向动力学特性的模拟是成功的.该模型可以用于汽车侧向动力学特性及其控制的研究工作.
A four-wheel-steering nonlinear lateral dynamics model of three degree of freedom including longitudinal motion was built based on Pacejka tire model. The simulation and the experiments by single lane, double lane change and slalom testify the identity of the experimental values and simulation values of related variants in time domain. The results demonstrate that the simulation of the nonlinear lateral dynamics for the lateral dynamics characteristics of the experimental vehicle is successful. The nonlinear model can be applied for the further research of vehicle lateral dynamics characteristics and its control.
