摘　　要：针对油液减振器的结构特性和工作原理,开发出了一种减振器异常噪声测试装置,通过对大量正常减振器和异常噪声减振器活塞杆头振动波形的衰减量进行特征分析,得出了减振器异响产生的原因和异常噪声减振器的鉴别方法,并对吉利自由舰MR7131A减振器异响问题进行了针对性的试验研究,分别讨论了异响发生与减振器阀片刚度、油液性能和活塞环大小等实际结构参数之间的对应关系,得出了研究结论。A device for shock absorber abnormal noise testing was developed based on the structure and principle of oil shock absorber. The reason of shock absorber abnormal sound and identification way of abnormal noise shock absorber were found out through sufficient attenuated analysis of rod vibration wave of the normal shock absorber and abnormal noise shock absorber. The abnormal sound from MR7131A shock absorber was studied as an example in order to discuss the relativity between abnormal sound generation and the real structure parameter, such as valve rigidity, oil performance and size of piston ring. The expected conclusion was drawn.
