On the wear prediction of the paper-based friction materialin a wet clutch.

A methodology for prediction of wear in the friction lining of a wet clutch subjected to repeated engagement cycles is presented. The wear mechanism is related to both thermal degradation and mechanical effects. The temperature history is obtained by performing a thermohydrodynamic (THD) analysis of the entire engagement process including engagement, soaking, dwelling and stabilization periods. The predictions of the model are in accordance to the experimentally observed “two-stage” wear rate phenomenon recently reported in the literature. [ABSTRACT FROM AUTHOR]
