The influence of friction blocks connection configuration on the interfacial tribology behavior and FIVN (friction-induced vibration and noise) of the high-speed railway braking system is systematically investigated with a scaled brake test bench. The potential relationship among interface contact status, friction, wear, pressure distribution, thermal response, and vibration noise of the system is studied under dragging test conditions. The results indicate that the connection configuration of the friction blocks has a significant impact on systematic interfacial tribology behavior, thermal response, and vibration noise. A floating connection mode can suppress the vibration noise of the brake system. The interfacial thermal response and systematic vibration noise are quite relevant with the contact status, interfacial wear, and pressure distribution. The increase of interfacial wear will lead to an expansion of pressure concentration area and an aggravation of vibration noise. This research is helpful for further design optimization and noise reduction of the railway brake system.
