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%.
