Clutch system is among the main systems inside a vehicle. Clutch is a mechanical device located between a vehicle engine and its transmission and provides mechanical coupling between the engine and transmission input shaft. Clutch system comprise of flywheel, clutch disc/plate and friction material, pressure plate, clutch cover, diaphragm spring and the linkage necessary to operate the clutch. The clutch engages the transmission gradually by allowing a certain amount of slippage between the flywheel and the transmission input shaft. However, the slipping mechanism of the clutch generates heat energy due to friction between the clutch disc and the flywheel. At high sliding velocity, excessive frictional heat is generated which lead to high temperature rise at the clutch disc surface, and this causes thermo-mechanical problems such as thermal deformations and thermo-elastic instability which can lead to thermal cracking, wear and other mode of failure of the clutch disc component. In this project, the thermal characteristics of the clutch disc is studied using finite element (FE) analysis method to identify the temperature distribution at the clutch disc in steady state phase. The thermal analysis is done using ABAQUS finite element software. Later, similar thermal analysis was carried out using different finite element software which is MSc. Patran-Nastran. Both results are then compared for better justification of the finite elements results obtained. The results provide better understanding of the automotive clutch disc thermal characteristics and helps m developing more efficient and effective clutch disc and the clutch system in general.
