Amelioration and Finite Element Analysis for Oil Groove of a Wet Clutch Friction Disk

摘要

The variable relation between oil groove section parameter and convection heat transfer coefficient have been researched at synchronization state under the condition of same flow area. On this basis, three oil grooves have been ameliorated, thermoplastic contact finite element model for the initial friction pairs and the ameliorated ones are created. After the distribution law of stress and thermal of friction pairs are gained, result shows that under the condition of same flow area, ameliorated oil groove can quicken the process of heat exchange, then more gentle temperature and stress gradient are gained, which can provide theoretic reference for wet clutch amelioration.
