In order to further explore the performance characteristics of disc brake in coal mine lifting equipment under emergency braking conditions,the shafless disc brake in a certain type of coal mine hoist was taken as the research object,and the emergency braking performance of the brake under different pressure,initial speed and friction coefficient was investigated by finite element analysis method.In view of this,the simulated annealing algorithm is further applied to optimize brake shoe parameters and brake disc parameters.The results show that the optimized brake can increase the positive brake pressure and further reduce the braking time,which proves the validity of this study.
