The Effect of Disc Radius on Heat Flux and Temperature Distribution in Friction Clutches

Abstract:

Friction clutch is an important machine element, which transmits the torque from the engine to the gearbox. Hence, an accurate estimation of the heat flux and temperatures on the friction surfaces is essential for proper design of the clutch to avoid failure due to thermal stresses. The dimensionless radius ratio (R=inner disc radius/outer disc radius) is the main key quantifying the quantities of heat flux and temperature on friction materials of clutch. Furthermore, the effect of (R) on the axial force, inner and outer radius, peripheral velocity and torque is investigated as well. The MATLAB and ANSYS have been used to perform the numerical calculation in this paper.
