Abstract The prediction of surface temperature induced by frictional heating
is of significance for evaluating the serious thermal wear, erosion
and lubrication failure for industrial application and design.
Temperature prediction model was established with two steps. Local
temperature was calculated firstly with the real contact area based
on the fractal analysis. Then, the finite element prediction model
were established with the above value of local temperature, on the
basis of wavelet finite element. Finally, the whole temperature of
the fractal engineering surface were demonstrated and simulation
results were shown. Moreover, orthogonal simulations were conducted
to study the influence of the input parameters of fractal dimension,
fractal characteristic length and material thermal properties.
Results with different cases demonstrated that all the temperature
decreased gradually from the contact surface to the bottom and the
temperature increased with the rise of heat transfer properties,
fractal dimension and fractal characteristic length for the same
position. However, heat transfer properties had the most obvious
influence on the temperature rise, and the following one was fractal
dimension.
