Paper Title:
Simulation Analysis on Wear-Resistance of Roller with Concave Surface
  Abstract

Three dimensional finite element model of roller and sheet rolling process was first built according to roller and flattening sheet rolling wear characteristics by using ANSYS/LS-DYNA software. Total 10 rolling models including 1 smooth surface and 9 non-smooth surfaces were established to compare with wear resistance characteristics difference. Simulation results showed that comparing with smooth surface roll sample, the non-smooth roller surface with concaves possessed had higher Von Mises stress value with non-uniform fluctuation at mean value in favor of enforcing rolling sheet fluidity. On the other hand, some air concentrated on concave circumjacent area will low adhesion wear appearance between plate and roller. Thirdly, Concave on the roller surface was also able to protect from sliding at friction interfaces. It was these factors above that were in favor of improving wear resistance capability of the rollers. The result of the model tests and the simulation are identical.
