Wear Simulation of the Mechanical Parts and the Probability Lifetime Estimation

Based on the discrete theory and computer technology,a normal simulation model was established by numerical simulation method.A concept of probability wear lifetime was presented.By Monte Carlo method,with the wear state of involute helical cylindrical gears as the object,an example was adopted to show that the calculation of the probability wear lifetime is realizable for the involute helical cylindrical gears.The simulation method and model solves the prediction for wear lifetime of components,which shows good prospects in practical engineering application.
