摘　　要：将螺旋理论应用于多连杆独立悬架运动空间分析中,采用螺旋理论中的运动螺旋来表示悬架的自由度和约束,并对悬架进行自由度和约束分析,总结出求解独立悬架这一类运动空间的分析方法,并举出算例。通过运动仿真来实现车轮在上、下跳动时悬架的复杂空间螺旋运动轨迹,这对研究汽车乘坐舒适性有很大帮助。This article applied the spiral theory to automobile multi-link independent suspension motion space analysis, used motion screw of helical theory to represent the freedom and constraint of suspension, and analysed the freedom and constraint of the suspension. It summed up the spatial analysis method used to solve the problem of independent suspension, and gave a calculation column. Through the motion simulation, the complex spiral trajectory of the suspension when the wheels jumped up and down was realized, which was of great help for vehicle ride comfort.
