Research on Braking Performance Using Scaling Methodology on Disc Pad in Disc Brake System

Abstract

Automobile is a big invention in itself, which comprises of engine, clutch, transmission, suspension brakes and other major components. Out of these components, brakes are the only vital components over which not much research has been done. Many advancements have been made in braking technologies over the time. Among which, disc brake system is the safest and advanced braking mechanism. The performance of a disc brake system depends upon parameters like heat generated, speed of the vehicle, rotor and disc pad material and other environmental conditions. Later on, these parameters result in stopping distance, braking power, deceleration time and thermal gradient, which depend upon disc pad and rotor contact region. If this contact region undergoes any change, parameters like temperature distribution, contact pressure distribution, total deformation and equivalent stress, it will ultimately get changed. This research paper emphasis on the using scaling methodology in disc pad to analyze and simulate the outcomes of changing measurements of disc pad in disc brake system. This paper aims to determine disc temperature and to examine stress concentration, structural deformation and contact pressure of brake disc and pads during single braking stop event. The thermal-structural analysis is then used with coupling to determine the deformation on both the assemblies. Temperature and equivalent stress analysis are carried out in fluent. The designs have been made in SolidWorks and analyzed in ANSYS workbench.
