“…Braking is achieved through the frictional dissipation of kinetic energy between brake pads and discs. The frictional parameters of brake pads, such as pad mass, pad-disc friction coefficient and pad stiffness, significantly impact the brake system’s dynamic characteristics, life span and wear (Lee and Jang, 2013; Lee et al , 2013; Yoon et al , 2012; Mueller and Ostermeyer, 2007; Wang et al , 2023; Xiang et al , 2021a). Noise and vibration during braking are among the challenges confronted by the transportation industry (Zhao et al , 2019; Cantone and Massi, 2011; Xiang et al , 2020).…”

Purpose This study aims to explore the impact of key parameters of brake pads on the dynamic characteristics of the braking system. Design/methodology/approach This study conducted experimental research based on a friction testing machine with a slider-disc structure. The experiment studied the impact of key parameters of brake pads (rotation speed, pressure, mass, braking radius, etc.) and the braking environment (dry friction, wetness, sand, etc.) on the stability of the braking system. At the same time, a dynamic model of the brake pad braking system was established and compared with experimental results using the mathematical tool of autocorrelation coefficient. Findings The key parameters of brake pads have a significant impact on the dynamic characteristics of the braking system; under different conditions of brake pad mass, tribological parameters, brake pad radius and braking environment, the chaotic characteristics of the braking friction force signal show a trend of expansion or contraction, which can be suppressed by adjusting the key parameters of brake pads. Originality/value This study can provide a reference for optimizing the braking strategy and reducing noise and vibration in brake pad systems.
