Abstract

An approximate method is developed to investigate thermoelastic instability (TEI) of the wet clutch system. By defining an equivalent friction coefficient, the frictional heat can be calculated and the critical speed can be deduced as in a frictional system without lubrication. Experimental investigation has been designed to estimate the equivalent friction coefficient. A theoretical model is developed on the basis of the Navier-Stokes equation and the Greenwood and Williamson's theory to deduce the coefficient that is corresponding to the experimental data. The effects of the fluid pressure on the coefficient are considered in the model. The critical speed is calculated by using the equivalent friction coefficient that accords with the result of the simulations.
