A model of friction for a pin-on-disc configuration with imposed pin rotation

摘要

A friction model is developed by considering the Coulomb friction model, a probabilisticudapproach of wear prediction, the kinematics of the pin-on-disc configuration and the elasticudtheory of bending. The model estimates the magnitude and direction of the frictional force, theudpin torque, the probability of asperity contact and the real area of contact distinguishingudbetween the part due to elastic and plastic asperity contacts respectively. Therefore, theudproposed model is suitable for the prediction of adhesive wear. It can be applied to metaludcontacts for conductance characterisation through the plastically deformed asperities which isudof great interest for electrical contact resistance studies.
