摘要
汽车的操纵稳定性是衡量汽车安全性最基本的指标之一,影响汽车行驶稳定性的基本因素主要有横摆角速度与质心侧偏角,将汽车简化为二自由度模型,建立关于横摆角速度与质心侧偏角的转向微分方程。基于MATLAB/Simulink软件建立仿真模型,对前轮转向与四轮转向典型的二自由度汽车模型进行仿真分析。对比两轮转向和四轮转向的稳定性。且四轮转向采用线控转向,将线控转向系统与四轮转向系统的优点结合起来,观察采用线控对汽车稳定性的影响。
Vehicle handing stability is the index to measure automobile safety.Yaw velocity and side slip angle are the basic factors that affect the vehicle handing stability.Simplify the car to two degree of freedom model.This paper establi-shed the differential equations of Yaw velocity and side slip angle.Using the MATLAB/Simulinl to create the simulation model and analyze the stability of Vehicle steering system.Combine the advantage of the wire steering system with four wheel steering,Observe its effect on stability.
