该文从车辆悬架系统的角度和减振器本体的角度对车辆筒式减振器侧向受力与摩擦进行了理论分析和试验 .提出了减振器硬系数等工程实用新概念 .文中系统归纳了使用国产设备进行减振器侧向受力与摩擦台架试验的技术路线与试验参数 In this paper, the lateral stress and friction of the tube-type shock absorber are theoretically analyzed and tested from the perspective of the vehicle suspension system and the body of the shock absorber, and a new concept of practical engineering of the shock absorber such as the hard coefficient is proposed. The technical route and test parameters for using the domestic equipment to carry out the lateral stress and the friction bench test of shock absorber are summarized
