Abstract: The friction braking mode of high-speed trains mainly converts the kinetic energy of the train into thermal
energy through the frictional action between the brake pad and the brake disc to achieve deceleration. Therefore, there is
a strong frictional action between the brake pad and the brake disc. The frictional action of the brake disc/pad is prone to
generate high-frequency, high-intensity friction-induced vibration and noise, and temperature accumulation at the
interface, which puts higher requirements and new challenges on the structural parameter design of the brake pad. As the
friction material on the brake pad, the friction block needs to exhibit sufficient and stable tribological performance
during the braking process of high-speed trains. The unreasonable design of the friction block will directly affect the
