Abstract: With the continuous improvement of high-speed train running speed and heavy load technology, the energy
dissipation density and thermal shock between the braking pads-braking discs friction pair have also increased
significantly, which undoubtedly constitutes a serious challenge for the friction and wear performance of the disc
braking system, especially the braking pads material as a wearable and necessary part. In this paper, from the perspective
of energy dissipation, the friction and wear behavior characteristics and wear life of dovetailed I-C type braking pads at a
speed level of 350 km/h with different cumulative cycle times (service cycles) were thoroughly investigated using a
high-speed pin-ring friction and wear tester instead of a 1:1 brake bench test equipment based on the principle of specific
experimental parameter selection. In addition, semi-in-situ wear experiments were carried out in order to characterize in
detail the damage mechanism of each component in the braking pads. The conclusions of this paper were as follows. The
average friction coefficient of the pin-ring friction pair under different number of cyclic experiments was mainly
