Static structural and thermal analysis of disc brake pad model

Abstract

This paper attempts to present a study of the automotive disk brake's thermo-mechanical behaviour during the braking period using the Static Structural and Transient Thermal analysis for vehicle disk brake pad system using finite elemental analysis. In this work Thermal and static analysis was performed on solid and ventilated disc for two configurations of pads using ANSYS 15. Two pad Profiles with pure and single slot along with both discs have been studied. The analysis is conducted on the model that lacks thermal properties first. It is predicted for structural performance such as deformation and von-mises stress. After that, with the introduction of heat flux, convection and adiabetic components, thermo-mechanical analysis is performed on the same model. The estimate results of temperature distribution, total deformation and von-mises stress are presented. The software tools CATIA and ANSYS Workbench have been selected for modelling and analysis. CATIA is a widely used 3D modelling technology in the design process. ANSYS is a software package for general purpose finite element analysis (FEA). The outcome of this investigation assists brake engineers in choosing appropriate research to determine the disk brake assembly in structural and contact behaviour.
