Abstract

This paper describes a sliding friction model for an electro-deposited coating. Reciprocating sliding tests using ball-on-flat plate test apparatus are performed to determine an evolution of the kinetic friction coefficient. The evolution of the friction coefficient is classified into the initial running-in period, steady-state sliding, and transition to higher friction. The friction coefficient during the initial running-in period and steady-state sliding is expressed as a simple linear function. The friction coefficient in the transition to higher friction is described with a mathematical model derived from Kachanov-type damage law. The model parameters are then estimated using the Markov Chain Monte Carlo (MCMC) approach. It is identified that estimated friction coefficients obtained by MCMC approach are in good agreement with measured ones.

摘要

本文描述了一种用于电沉积涂层的滑动摩擦模型。使用平板对球试验装置进行往复滑动试验，以确定动摩擦系数的变化情况。摩擦系数的变化分为初始磨合阶段、稳态滑动阶段和向更高摩擦的转变阶段。初始磨合阶段和稳态滑动阶段的摩擦系数表示为简单的线性函数。向更高摩擦转变阶段的摩擦系数用从卡恰诺夫型损伤定律导出的数学模型来描述。然后使用马尔可夫链蒙特卡罗（MCMC）方法估计模型参数。结果表明，通过MCMC方法得到的估计摩擦系数与测量值吻合良好。
