【Abstract】 Based on the finite element method, the thermal stress-stain field character of brake disc is studied in this paper. Considering the material mechanical property parameters, the thermal fatigue life of the brake disc is assessed and the results show that the finite element calculation results are consistent with that of low period fatigue specimens. For the more, the assessing method of fatigue life of brake disc has been provided.更多还原
