Comparative Study Of Thermal Analysis Of Solid And Ventilated Disc Brake

Mechanical Engineering

Braking is a process which converts a vehicle’s kinetic energy into mechanical energy which is to be dissipated in the form of heat. During the braking process, the frictional heat generated at the interface of the disc and pads can lead to high temperatures. In this paper, work is present in the form of result of transient thermal analysis of disc brake disc used in four-wheeler . The aim of this paper is realize the purpose of holes on the disc brake. the thermal analysis is done for two different models of disc. One is a simple disc without vents and holes and the other perforated (consists of holes). Researchers have tried to analyze the heat loss from a disc which is considered to be heated by disc brake friction when in use. Researchers analyze the heat loss taking into account convection and radiation. The results are compared for both the discs. The initial condition assumed here is that the vehicle has stopped completely by application of brakes. Both the disc are of same dimensions. The geometry of disc brake rotor is made in Creo parametric 2.0 . The heat transfer analysis is done using ANSYS workbench 14.5. The analysis helps us to understand which of the two models is better in terms of performance, heat loss and hence extensively used in four wheeler in real world.
