【摘要】：基于接觸界面勢壘與摩擦接觸面形貌的隨機特性,建立了一種新的納米級粗糙表面滑動摩擦力計算模型;利用該模型對滿足嚴格平穩(wěn)的同種摩擦副材料納米級隨機粗糙表面的摩擦力進行了數(shù)值計算.結果表明:經該模型數(shù)值計算得出的平均滑動摩擦力與法向載荷呈線性關系;法向載荷與平均接觸界面間隙呈指數(shù)關系;在相同界面間隙下,平均法向力與粗糙峰高度分布標準差呈線性關系.計算結果與現(xiàn)有的研究結論相符,證明該模型是有效的、可行的;基于該模型,可根據(jù)接觸界面的形貌分布參數(shù)、材料參數(shù)與法向載荷預測出平均滑動摩擦力.
[Abstract]:Based on the random characteristics of the contact interface potential barrier and the morphology of the friction contact surface, a new model for calculating the sliding friction force of the nanometer rough surface is established. The model is used to numerically calculate the friction force on the nano-scale random rough surface of the same friction pair which satisfies the strict and stationary condition. The results show that the average sliding friction force is linearly related to the normal load, and the normal load is exponentially related to the average contact clearance. There is a linear relationship between the mean normal force and the standard deviation of the height distribution of the rough peak. The calculated results are in agreement with the existing research results, which prove that the model is effective and feasible. Based on the model, the average sliding friction force can be predicted according to the profile distribution parameters of the contact interface, the material parameters and the normal load.
