Analysis of key brake pad parameters on brake system stability

Abstract

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.
