"Effects of load, speed and slip angle on wear behaviors of natural rubber composites"

Abstract

The effects of load, speed and slip angle on the abrasion and surface temperature of natural rubber composites were investigated using LAT 100 laboratory abrasion tester, and the relationships between energy loss and abrasion, side force and wear surface morphology during the abrasion were established. The results showed that the abrasion and surface temperature of natural rubber composites increased with the increase in load, speed and slip angle. The slip angle had the greatest effect on the abrasion and surface temperature of natural rubber composites, the speed had the least effect on the abrasion of natural rubber composites, and the load had the minimal effect on the surface temperature of natural rubber composites. The effect of friction force on abrasion was much smaller than that of side force, the abrasion of natural rubber composites had an exponential relationship with the energy loss during the wear process, and the exponent was about 2. The abrasion was the severest in the slip region of natural rubber composites, and the area of the slip region was determined by the distribution of side force in the contact area.
