车辆转向回正因素分析

Analysis of the Factors of the Vehicle's Turn-back

转向回正是车辆的动态特性之一,当车辆在运动中出现转向操作,前轮有转向角度输入,此时车辆就会产生一个绕主销的回正力矩,使车辆向恢复直线行驶状态变化。文章从理论角度分析了影响产生转向回正的因素,定量分析了各因素的敏感性并试图给出了解决方案。

Steering return is one of the dynamic characteristics of the vehicle.When the steering operation occurs and the front wheel has steering angle input,the vehicle will produce a positive moment around the main pin,which will change the vehicle to a straight line.From the theoretical point of view,this paper analyses the factors affecting the turning back,quantitatively analyses the sensitivity of each factor and gives the solution.
