A Characteristic on Abrasion Pattern on a Sliding Surface of Rubber under Stick-Slip Motion

Abstract

An ultrasonic technique was developed to study the characteristic abrasion pattern on a rubber surface under stick slip motion and to demonstrate the precisely contact pressure measurement at the end of contact. Experiments were conducted using short cylindrical rubber specimens pressed onto the rotating acril disk. It was observed that the abrasion pattern was significantly dependent on the variation in contact pressure. In addition, the experimental results showed that the formation of abrasion pattern on the middle area of contact was stimulated by the stick slip motion.
