摘　　要：从减小冲击车辆的角度,初步分析了当负重轮以较高速度抬升时车辆对减振器阻尼特性的总体要求。根据液力式和摩擦式2种减振器的阻尼特性,针对2种车型的减振器联动杠杆机构,用图解法分别分析了负重轮在相同摆动速度和相同受力条件下,经联动杠杆作用后减振器摆臂运动速度和受力的变化趋势,并据此对这2种车型和2种形式的减振器阻尼与车体阻尼需求的匹配情况进行了评述。结果表明:联动杠杆对减振器性能的发挥存在影响,所分析的2种车型的杆系和使用的减振器性能配合不够理想。In terms of reducing shock on running vehicle,general requirements for shock absorber damp-ing characteristics are analyzed when road wheels rapidly uplift.Based on damping characteristics of two types of shock absorber,i.e.hydraulic and friction,variation of velocity and force of swing arm for the linkage lever mechanisms of two types of vehicles under the same swing velocity and force of road wheel is analyzed with graphical method.Problems of matching absorbers’damping characteristics with vehicles’ requirements are discussed.The results show that the linkage lever mechanisms have influence on shock absorber property,and the linkage lever mechanisms of two types of vehicles aren’t matching well with the shock absorber characteristics.
