摘　　要：转向系统性能作为整车性能的一部分,是驾驶人员最直接、最容易感受的属性,但力矩波动又是转向系统性能重要的因子,它直接影响驾驶员对车辆的感觉,因此解决好力矩波动非常关键。同时,力矩波动波峰波谷所处位置,对驾驶感也是特别重要的评价因素。文章阐述了力矩波动的计算方法及Catia仿真,并介绍如何设定转向系统相位角。As a part of the vehicle performance,steering system performance is the most direct and easily felt attribute of drivers.But torque fluctuation is one of the most important steering system factors.It directly affects the driver’s perception of the vehicle,so solving the torque fluctuation is very critical.At the same time,the location of the peak and trough of torque fluctuation is also an important factor to driving feeling.This paper describes the calculation method of torque fluctuation and Catia simulation,and introduces how to design the phase angle of steering system.
