摘　　要：On the basis of analysing the outer performance degradation of shock absorber on suspenson and from the relationship between outer and inner performances of the shock absorber, an internal relationship between the structure design and degradation of the shock absorber is discussed in the paper. From dynamic property, analysed the dynamic cause for degradation, the paper proposes a technical method of improving outer performance and a concept of critical velocity, and discusses what effects the critical velocity and the outer performance mance degradation has.在研讨悬架减振器外特性空程性畸变的基础上，从减振器内特性和外特性的关系出发，探讨了减振器结构与畸变的内在关系．从动态特性出发，分析了畸变产生的动力学原因，提出了改善外特性的技术途径，并对减振器畸变临界速度的影响因素及其与外特性畸变的关系进行了探讨．
