1) The document analyzes drum brakes, which convert kinetic energy to heat during braking. Drum brakes experience high temperatures and thermal stresses. 2) The literature review discusses previous research on drum brake design modifications to improve heat transfer and reduce weight, stress, temperature, vibration and noise. Previous studies examined adding fins, optimizing wall thickness, and using alternative materials like aluminum alloys. 3) The proposed research aims to further reduce heating, increase braking efficiency, modify shoe materials, add fins, reduce costs and improve reliability through experimental testing of drum brakes with rectangular, triangular and circular fins. Thermal analysis will examine temperature rise with different fin designs.
