Relation between tread wear and frictional work using FPS abrader

Wear experiment of tire tread rubber was conducted using FPS (Field Performance Simulation) abrader manufactured by UESHIMA SEISAKUSYO Co. Ltd., Japan by changing the severity. The relation between frictional work and wear rate were obtained. The normal load varied in 10 N, 20N, 40N and the circumferential speed of rubber specimen was 50, 100, 150, 200 m/min, respectively. The slip speed varied in 1, 10, 20 m/min by changing the slip ratio from 0.5 to 40%. As a result, Certain relation between introduced frictional work and wear rate was obtained. The relation varied as the applied normal load changed.
