摘要
针对车辆操纵稳定性研究中常用的两轮二自由度模型存在的问题,提出了四轮二自由度模型,应用Matlab/Simulink对四轮模型与两轮模型进行了对比分析。仿真计算表明,四轮模型在不同转向角、不同车速以及轮胎线性和非线性条件下均能很好地描述车辆的操纵稳定性。
The problem was studied on a 2 - DOF two - wheel model, which is usually used in researching into vehicle handling stability. A 2 - DOF four - wheel model was developed. The four - wheel model was analyzed by contrast with two - wheel model with Matlab/Simulink. The simulation results indicate that the four- wheel model can be used to study on vehicle handling stability be the same with different steering angle,speed and linear or nonlinear tire model.
