In this work, the Finite Element Method
(FEM) is used to analysis contact temperature of
multiply asperity sliding contact surface. The following
parameters are included: pressure, roughness, sliding
speed, friction coefficient, and thermal conductivity.
Analysis results show that pressure and thermal
conductivity play the most important role on affecting
maximum temperature rise parameter. In addition,
regression equations are used to study the effect of study
parameters on the contact temperature for roughness
surface. The effects of contact pressure and thermal
conductivity on the contact temperature increases as the
Peclet number increases.
