Abstract
Because of the need for safety, braking performance has become a very important factor for automotive manufacturers and passengers. Despite all the stresses experienced by the drum brake doesn’t damage the drum due to high tensile strength but the drum may fail under fatigue loading. The critical region of concentrated stress is determined, and appropriate modifications are being made to improve it. The distribution of stress and the heat dissipation obtained from the result of the analysis are employed as input for the failure region. The findings of stress and thermal analysis are crucial for improving the component design at the first stage of development. The objectives of this study are to modify and improve the circumferential strength and heat dissipation and to optimize the design of the drum brake with simulation using Finite Element Analysis. The simulation was run on the initial model and modified on its to make it better. it shows that 27.33% decrease in maximum von Mises stress. Thermal analysis for heat flux on the material will show the ability of heat dissipation. Overall, It has been determined that aluminium alloy is the optimum material for drum brake design in terms of total heat flux.
