摘　　要：根据工程实践,提出了通常在计算汽车底盘悬架系统的悬架垂直刚度时被简化的,但却很重要的无簧悬架刚度的概念,介绍了一种无簧悬架刚度的简易测量方法。由测量得到的无簧悬架刚度曲线的迟滞现象,引申出悬架摩擦的概念,分析产生悬架摩擦的原因,及其对行驶平顺性的影响。Based on engineering practice an important concept is presented here.The concept usually is reduced during calculating suspension perpendicular rigidity of chassis suspension system.A simple measurement for rigidity of chassis suspension without spring is produced.A hysteresis of the rigidity curve is obtained from the measure.And a concept of suspension friction is derived.The paper analyzes the reason of suspension friction and the influence to ride performance.
