The friction clutch is considered a very important element of machines, as it plays a major role in transferring power from the driving part to the driven part. A common application of the friction clutch is in vehicles to connect between the gearbox and the engine. Fast wear occurs as a result of frictional heating that is generated when the clutch is starting to engage. This wear, in addition to the high thermal stresses, will lead to premature failure in the contacting surfaces. The present review highlights the most important studies of the thermal and thermoelastic problems of friction clutches during the last 10 years to show the challenges that were overcome and also the other challenges that needed to find solutions. The present paper will discuss in detail the influence of the frictional heat generated between contact surfaces during slipping and the main factors affecting the thermal behavior of dry friction clutches, such as sliding speed, friction materials, applied pressure, and so on. Furthermore, significant conclusions and remarks based on the available solutions to the thermal problem of the clutch are presented.

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.

Clutch components rotating at high speed remain under the influence of high centrifugal forces. Therefore at the high rotational speeds flywheel is subjected to extreme forces that may cause severe cracks and breakages. Burst test validates the mechanical robustness of the flywheel under various rotational speeds. In this study comparative analysis have been performed experimentally and numerically in order to confirm correlation of the results. Centrifugal endurance test called burst have been performed in addition to finite element analysis which has been used for calculating stress values of flywheel. Additionally design of experiment method has been used for obtaining the response surface that approximates the stress behavior of automobile flywheel. This provides strong correlation between FEA results and data fittings calculation that gives extra contribution to reduce the design process. This study gives ideas for the stress improvement of flywheel by making experimental and numerical comparison. Experimental and numerical correlations results taken from this study can be used on the estimation of design robustness instead of prototypes production which causes time and money consumption during flywheel design and production process.
