The background and necessity of application of numerical simulation method in research on friction materials
of automotive brake are analyzed. The numerical analysis methods of conversion of braking energy, distribution of friction
heat, transfer of friction heat and thermal mechanical coupling, are discussed. The dynamic temperature field and
thermal stress field of the same brake disc and two kinds of friction plates of different materials, which are the composite
materials based on resin and the powder metallurgy based on copper, are simulated and analyzed respectively under emergency
braking. The effect of friction materials’ performance on friction temperature and thermal stress distribution is obtained.
The results show that the friction performance of composite materials based on resin is better than the powder
metallurgy based on copper. The results are consistent with the experimental results. The numerical simulation methods
proposed have a good predictive effect on the typical characteristics of friction materials in the process of braking, which
provides effective references for preparation and optimization design of friction materials of brake.
