摘要:

为精确量化湿式摩擦元件的温度场失效概率问题,先建立热-机械耦合仿真与单对粗糙峰接触模型实时交互的宏微观摩擦模型获取温度,再构建温度场失效概率统计模型。利用核密度估计建立失效参数的概率密度函数,采用蒙特卡罗模拟进行了概率计算。试验结果表明,仿真与试验的数据高度吻合,所建立的统计模型能有效且精确计算湿式摩擦元件的失效概率。

Abstract:

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 emploied 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.

Key words: wet friction pair, failure probability analysis, macro-micro interaction, kernel density function, Monte Carlo simulation
