摘　　要：主要研究了隔膜泵曲柄滑块机构连杆小头与滑块连接副松动的非线性特性。将连接松动按照磨损故障来考虑,采用接触—分离二状态接触力模型,考虑了运动副元素接触表面的线弹性变形和阻尼,建立了相应的动力学模型。通过数值仿真,研究了曲柄不同转速下的动态响应,同时为往复机械的磨损动力学分析提供了有参考价值的结论。The primary goal of this research is the non-linear properties of the loose joint of membrane pump＇s connecting rod and slider.The author looked the loose joint as a worn one.According to the contact-separation state contact force model,taking account of the elastic deformation and damper of viceline element＇s contacted surface,a dynamic model was established.The relations between different rotate speed of the crank and the slider dynamic response were investigated by numerical simulation.all these are useful for the dynamic analysis of reciprocating machine.
