Dynamic Response Analysis on Connecting Rod Bearing Shell of Reciprocating Machinery with Abrasion Fault
摘要
Abstract
As one of the most severe faults of the reciprocating machine,the abrasion fault of the connecting rod bearing shell is difficult to predict for its complex fault excitation.The multi-body dynamic model of the connecting rod bearing shell with abrasion fault was built based on the nonlinear contact model and nonlinear friction model.The deteriorating process of the fault was simulated by changing the clearance size between the crank shaft and the connecting rod bearing shell,and the changing rules of the contact force and the response characteristics of reciprocating machinery were analyzed during the process.The method for prediction and diagnosis of the fault is proposed in the research.关键词
