Thermal Analysis of Disc Brake using Ansys Software

Abstract

The objective of this study is to analysis the thermal behaviour of the non-vented (solid) disc using ANSYS
software. The Reliable and effectual braking is an imperative requirement of safe transportation. The disk brake generally
has a high braking ratio and alleviates the thermal load of the wheels, therefore it has been extensively used in vehicles.
Disk brakes are persistently showing to large thermal stresses during routine braking and are subject to unexpected
temperature distribution during hard braking. In this study solid disc brake rotor of vehicle has been taken in investigation
which is made of martensitic stainless steel and Ceramic material. These materials have been selected to improve the
braking efficiency and provide better stability to the vehicle. The modelling of disc brake rotor is done using solid works
and the thermal analysis of disc brake rotor has done using ANSYS software (ANSYS 15). ANSYS software has been used
for determining the variation of the temperature and heat flux across the disc brake profile. A comparisonal study has been
made between two different materials used for solid type disc brake and the best material for making disc brake have been
suggested on the basis of magnitude of temperature distribution and total heat flux. The computational results are
presented for the temperature distribution and heat flux on each friction surface between the disc and pad. After the
investigation result of temperature distribution and heat flux of the Ceramic material was found excellent.
