THERMOELASTIC ANALYSIS OF MULTI-DISC CLUTCHES USING FINITE ELEMENT METHOD

The high thermal stresses generated between the contacting surfaces of a multidisc clutch system (pressure plate, clutch discs, plate separators, and piston) due to the frictional heating generated during slipping are co...

THE CHANGE OF FRICTION AND LOAD- CARRYING CAPACITY OF THE JOURNAL BEARING WITH THE CONSIDERATION OF THE OIL AGEING

This paper presents numerical calculations of the hydrodynamic pressure distribution, carrying capacity, and friction coefficient in the gap of a journal bearing. The analysed bearing is lubricated using motor oil. In th...
