Failure Probability Analysis of Temperature Field in Wet Friction Components Based on Macro-Micro Frictional Contact Model

Aiming at accurately quantifying the failure probability of temperature fields for wet friction components, a macro-micro friction contact model, with the interaction of thermal-mechanical coupling simulation and single asperity contact model, was established to acquire temperature, and a statistical model for temperature field failure probability was constructed. The method utilized kernel density estimation to establish the probability density function of failure parameters and employed Monte Carlo simulation for probability calculation. Experimental results show high agreement between simulation data and test data. The established statistical model may effectively and accurately calculate the failure probability of wet friction components.
