转向系统力矩特性理论研究与仿真分析

Theoretical and simulation analysis of steering system torque characteristic

转向系统作为不可或缺的底盘零部件之一,其驾驶时的力矩表现关系到整车的安全及驾驶感受。文章对转向系统的力矩特性进行了理论研究及仿真数据分析,得出转角、整车侧向力以及重力回正力矩与转向力矩的关系,一定程度上,为分析及优化转向力矩提供了理论参考。

Steering system is one of the necessary parts for the vehicle.Moreover,the steering torque performance is related to vehicle dynamic driving safety and feeling.This paper focuses on the theoretical analysis and simulation of steering system torque characteristic.The result shows the relationship between steering angle,lateral force and gravity returning torque and steering torque and will provide a reference for setup or optimization of steering system torque.
