Determination of Temperatures Field for Multi-Disc Clutches

A clutch system is one of the most important components of a vehicle that plays a vital role in the transmission of power and control of motion from one component to another. The main task of the clutch is to connect and disconnect the driving (engine) and the driven (gearbox), and assist a gentle engagement. This paper presents full details to compute the temperature field and contact pressure distribution of the multi-disc clutch during the beginning of engagement (sliding period). Finite element method is used to obtain the numerical simulation of transient thermoelastic behavior of a dry clutch system. The applied pressure during the slipping period assumed to be constant and the effect of convection is neglected. This work shows the effect of sliding speed on the temperature field and the contact pressure distribution for the multi-disc clutch system.
