Abstract

The work deals with the analysis of heat generation and dissipation in a solid disc brake of a motor cycle during continuous braking by using computer -aided engineering software with two disc profile and three different materials of the rotor disc. The objective of this work is to investigate and analyze the temperature distribution and heat dissipation (steady- state thermal analysis) of the rotor disc during braking operation. The work uses the finite element analysisze technique to predict the temperature distribution on the disc rotor and to identify the critical temperature of the brake rotor disc. All three modes of heat transfer (conduction, convection, radiation) have been analyzed. The three different materials studied are Grey Cast Iron, Aluminum Alloy 6262 T-9 and Carbon-Ceramics with two different profiles of disc rotor. The results obtained from the analysis shows that different material on similar load conditions during continuous braking shows different temperature distribution. Thus, a comparison is made between the three materials used to know the best material for making disc brake rotor based on the rate of heat dissipation and critical temperature. Hence, it is found that Aluminum Alloy is the most appropriate material among all three material selected for solid disc rotor.
