摘要

针对高速运动下的摩擦副如滑靴与轨道之间存在摩擦磨损且实际工况下摩擦系数难以测定的难题

提出了一种利用有限元计算摩擦系数的数值研究方法。基于W-M函数法

利用MATLAB对不同粗糙度下的表面轮廓完成了数值模拟分析

采用ABAQUS二次开发

实现了在有限元中快速建立粗糙表面模型的功能。以此为基础

对滑靴在运行过程中摩擦系数的动态变化规律进行了研究

得到了摩擦系数与载荷、速度之间的数学关系模型。通过销盘磨损实验对其部分仿真结果进行验证

实验结果与公式预测误差在10%以内

证明了该数学关系模型的有效性

为高速下干滑动摩擦特性的研究奠定了基础。

Abstract

Considering the difficulty of measuring friction coefficient under actual working conditions

a numerical method for calculating the friction coefficient with finite element analysis is proposed to solve the complex friction and wear phenomenon between the slipper and the track at high sliding speeds. By means of W-M function method

MATLAB is used to complete the numerical simulation analysis for surface contour under different roughness

then the function of quickly establishing rough surface model in the finite element is reali-ed via secondary development of ABAQUS. The mathematical model of friction coefficient

pressure and velocity is obtained by analy-ing dynamic variation law of friction coefficient during running of slipper. The simulation results are verified by the pin plate wear experiment and it is found that all errors are below 10%.
