Abstract [en]

Wet clutches are critical components in many automatic transmissions in the automotive industry. These components handle large amounts of energy through sliding friction as they engage during machine operation, resulting in clutch disc wear. Wear experiments at high clutch engagement energies has revealed that a change in the friction material wear rate can occur at some point during the test, i.e. transitioning from a low to a high wear rate. This brings into question the conventional way of performing wear tests i.e. measuring a specimen before and after testing and the usual way of viewing wear i.e. as a constant wear rate after running in. The authors propose a two step wear model to describe the wear that can occur under some conditions exemplified in this paper.
