Brake Friction Material

This work investigates the effect of road grit particles and material compositions on disc brake squeal noise. Three different Non Asbestos Organic (NAO) brake pad samples and road particles with a size range between 400 μm to 500 μm are used in the squeal experiment. The relationship between the existence of road particle with the noise occurrence were studied through the change in pressure level, friction coefficient (CoF), sound pressure level (SPL) and material composition. The material compositions were analyzed before and after squealing condition using energy dispersive X-ray analysis (EDX). Result has shown the road particles contribute to the emission of squeal noise and the increasing of some material composition of brake friction material components.

Friction Induced Vibration

In this paper, the friction-induced vibration of a simple disc brake model during decelerated sliding is investigated. A three-degree-of-freedom physical model of a disc brake system is considered; the brake pads are modeled as rigid blocks interacting with a rigid translating strip (rotor) through friction. This model simulates the transient dynamics of the longitudinal motions (in the direction of sliding) of the pads during braking. A Coulomb-type friction model is adopted, with the coefficient of friction approximated by an analytical function of the sliding speed at the rotor-pads interface. The coupled equations of motion for the longitudinal vibrations of the sliding strip and the pads are solved simultaneously. Effects of the friction model and other physical parameters on the transient dynamics and instability of the system are examined through the numerical results. Implication of these results to brake squeal generation is also discussed.
