Cover Story: The braking system is essential for the steady and safe operation of trains. The friction blocks installed on the brake pad have different friction radii, which significantly affect the stick–slip characteristics of braking systems. In this research, the stick–slip vibration properties of the friction blocks with different friction radii were experimentally investigated using a block-on-disc configuration. Additionally, the Stribeck model parameters of the disc–block friction interface were identified to reveal the relationship between the stick–slip vibration and the friction coefficient. The results can provide a reference for understanding the stick–slip characteristics and stability of the train braking friction blocks at different friction radii. View this paper
