ABRASIVE WEAR MODEL FOR LUBRICATED SLIDING CONTACTS

A lubricated wear model for stochastic rough surface in sliding contac ts is presented. In this model, the visco-elastic characteristic of th e solid, the effects of surface roughness profiles, hardness of materi als and operating conditions are included. The reasonableness of the m odel is proved by comparing calculated values with the test results on a ring-on-block test machine. They coincide well. From the model, the relationship between wear rate and film thickness ratio can be deduce d. It provides a theoretic basis for wear prediction and prevention.
