Abstract：One of the most critical system of CRH EMU(China Railway High-speed Electric Multiple Units) is breaking system,while most of the brake pads are imported with high cost.A new type of break pad is proposed based on interchangeability and practicability.Taking the new type of break pad as an example,ABAQUS Finite Element software is applied to obtain yon Mises stress of the key contacting components in the most dangerous condition.Furthermore,fatigue life of the key contacting component is calculated by fatigue life transition.The results show that the new type of break pad can meet the requirements of strength and fatigue,so it is possible to carry out the installing test to promote the localization process of brake pads.
