Design and thermal validation of four wheeler disc brake using different material

Abstract

Safety concern in a vehicle plays a major role in development of any vehicle. Hence each and every vehicle has been studied in order to meet their safety requirement. In which, braking system is one of the major concern in safety as well as during breaking the heat is rejected to environment which leads to increase of global temperature. In this paper, the study of thermal analysis is carried out in rotor type disc brake with design modification as with and without cross drilled holes for various types of materials such as stainless steel, cast iron and aluminium alloy. Disc brakes are exposed to large thermal stresses during routine braking and extraordinary thermal stresses during hard braking. In order to overcome the thermal stress, disc brake rotor type is designed with cross drilled hole. The design is carried out by using CATIA V5 R21 and thermal analysis is carried out by using ANSYS. The result shows that the aluminium material with cross drilled hole has high thermal capacity for braking system among the other two materials such as cast iron and stainless steel.
