Comparative Analysis of Disc Brake Model for Different Materials Investigated Under Tragic Situations

Abstract

The paper focuses on the modelling, analysis and design of disc brake under tragic situations for maximizing the heat dissipation and minimizing the brake release period. The main objective of this paper is to examine and analyze the temperature distribution in disc brake during tragic running condition. Finite Element Analysis (FEA) techniques are used to envisage the temperature distribution and to spot the critical temperature on the disc for diverse materials using analysis software COMSOL MULTIPHYSICS. The brake disc model is analysed for four different materials with simple geometry. The basic features of the disc brake are designed based on the three modes of heat transfer i.e. conduction, convection and radiation and are analyzed using COMSOL MULTIPHYSICS. The results obtained from the analysis illustrate diverse temperature characteristics for each material. Finally, a comparison is made for four different materials and the best material is selected under given constraints by optimizing the rate of heat dissipation and brake release time.
