Study the influence of repeated braking on the thermal behavior of brake system using experimental work

Abstract

During the repeated braking, it will generate high amount of heat on the braking disc and braking pads. The value of the generated heat depends on many factors such as the vehicle speed, materials properties, disc brake construction, as well as the number of braking cycles. The aim of this paper is to investigate the effect of repeated braking on the temperature distribution of the braking pads and disc. It was performed the experimental approach under the laboratory conditions without air flow. It was found that the temperatures of disc and pads increase significantly with each new cycle of braking. It was found that magnitude of the friction coefficient has great influence to reduce the braking distance. The obtained experimental results can be applied in the design and manufacture the brake system of the automotive vehicles based on the safety factor of passengers. In the other words, keep the heat generation within the limit.
