In this paper, authors present our results of thermal analysis of disc brake rotor used by two-wheelers in India. The aim of this paper is to realize the purpose of the holes in the disk brake. Thermal analysis is done for two different models of rotors. One is a simple rotor without vents and holes and the other perforated (consists of holes). Researchers have tried to analyze the heat loss from a rotor which is considered to be heated by disc brake friction when in use. Researchers analyze

... 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 rotors are of same dimensions. The geometry of disc brake rotor is made in Solid-Works. The heat transfer analysis is done using ANSYS software. The analysis helps us to understand which of the two models is better in terms of performance, heat loss and manufacturing cost and hence extensively used in motorcycles in real world.
