The Life Prediction Model of Vehicles Engine Based on Cylinder Wear-law

摘要：

　　The wear-law and the life prediction model of mechanical components were analyzed.Supposing the mean wearing rate of cylinderduringthe stable wear period obeys normal distribution,the samples of cylinder life was acquired applyingthe time-step Monte Carlo simulation method,and the life distribution function of cylinder wear was defined applying Kolm oglov hypothesis test.Finally,the life prediction m odel of vehicles engine was build based on cylinder wear-law.The example proves that the model build here can predict the life of gradual changed components,and it well compliant to predict the life of vehicles engine.
