Abstract：Through finite element modeling of the automobile disc brake,the temperature and stress distribution of the brake emergency braking condition and the continuous braking condition were obtained.Under the premise of not changing the whole structure of the brake,diameter and thickness of the brake disc and the inner diameter and thickness of the friction block were defined as the design variables,maximum temperature and stress were defined as optimization objectives,finite element method,response surface method and NSGA-Ⅱ algorithm were used in the optimization of the brake.After optimization,the maximum temperature of the brake was reduced by 13%,the maximum stress was reduced by 15%;Bench test was made to optimized brake.Results showed the experimental value matched well with simulation value and proved the feasibility of the optimized design.
