| Abstract: |
| The working conditions and requirements of the corresponding materials of the friction pair composed of brake pad and brake disc in disc brake device for rail transit vehicles are analyzed. The characteristics and application fields of cast iron, resin-based brake pad and powder metallurgy brake pads are summarized. The main focus is on the analysis of the functions of varied components in iron-based and copper-based powder metallurgy brake pads, as well as the key factors that determine their friction and wear performance. Based on the formation mechanism of hot spots on brake discs, the effect of shape and arrangement of brake pads on the heat distribution of brake disc is analyzed. Moreover, the development of cast iron, cast steel, forged steel, metal matrix composite, and C/C composite brake disc is elucidated briefly. Finally, the key research directions on the design and manufacture of the brake materials for modern rail transit are also proposed.
