Abstract:
Stress distribution of strip steel coating line roller was analyzed by finite element model(FEM). Effect of strip wrapping angle, rubber layer thickness and strip tension on stress distribution of roller were discussed respectively, and fitting model of maximum Von mises stress on roller was developed. The computational results indicate that the maximum stress always appears where the rubber roller is to contact the strip steel and the magnitude of wrapping angles has no effect on stress value. Maximum stress on roller is in exponential relationship with wrapping angle, increases with the thickness of rubber layer and is proportional to strip tension.
