基于转向半径的汽车稳态转向特性分析

汽车等速行驶时，常用稳态横摆角速度与前轮转角之比来评价其稳态响应。根据稳定性因数的数值不同，可将汽车的稳态转向特性分为三种类型：不足转向、中性转向和过多转向。本文通过几何学、车辆运动方程式，分别推导出汽车转向半径公式，在各相应的条件下，分别基于转向半径公式对汽车三种稳态转向特性进行分析。

The Analysis of Steady-State Steering Characteristic Turning Radius-Based in Vehicle

The steady-state response of a vehicle is often evaluated by the steady-state yaw velocity and front wheel angle at a equal speed. On the basis of difference in stability factors, the steady-state steering characteristic can be divided into three styles: under-steer?neutral-steer, over-steer. This paper separately deduces the turning radius formulas through the geometry and movement equation of vehicle at their relevant conditions, and then has analysis of three style of steady-state steering characteristics turning radius-based.
