As well known the shock absorber is a key part of auto & motorcycle that is easy to be failure . the guide bushing & piston rod is also easy to fail mostly in the shock absorber . therefore it is very important practical and theoretical meaning to study friction & wear mechanism during this reciprocating movement 减振器是汽车、摩托车中一个关键的易损零部件，主要是内部导向套?活塞杆这对往复运动摩擦副的失效导致，因此研究此类型往复运动的摩擦磨损机理具有十分重要的实际意义和理论意义。
