Most of failures in the friction clutches occur due to the excessive heat generated due to friction between various parts, and this heat causes high temperatures leading to high thermal stresses. In the present research paper, numerical simulation had been developed using finite element method to simulate the thermal behavior of the dry friction clutch. Three-dimensional finite element model was made and analyzed using ANSYS/Workbench sofware18. The friction clutch system was firstly modeled mathematically and solved numerically to determine the transient thermal response of the clutch disc. The two fundamental methods of uniform wear and uniform pressure are assumed. The applied torque during the sliding period was constant. The temperature and heat generated were estimated for each clutch part (pressure plate, clutch disc and flywheel) using heat partition ratio. The assumptions that are inherent in the derivation of the governing equations are presented which followed up by the appropriate boundary conditions. The results show that the maximum temperature values for uniform pressure condition are greater than those for uniform wear condition. Also, the temperature value increased with time and approximately reaches the highest value at the middle of the sliding period when the applied torque is constant with time and then decreased to the final values at the end of slipping period.Refference:
