THREE-DIMENSIONAL SIMULATION OF THE THERMAL PROBLEM IN FRICTION CLUTCHES USING FINITE ELEMENT TECHNIQUE

Abstract

This research paper presents a new numerical model of the single disc clutch that works under the dry conditions, whereas this model simulates the actual model in terms of geometry. It was overcome the difficulties that which faced the researchers in the previous literatures to build the three dimensional model of friction clutch. It was investigated deeply the thermal problem that occurred during the sliding period when the friction clutch starts to transfer the torque. In this paper, the finite element technique was applied to implement the thermal analysis. The developed finite element model was verified by comparing the obtained results with results of the other researchers that used different approaches. Moreover, the influence of the sliding speed on the thermal behaviour of the clutch disc has been studied.
