碩士 === 高苑科技大學 === 機械與自動化工程研究所 === 98 === This study assumes constant shear friction to perform FEM simulation of asymmetrical rolling of double-layer bounded clad sheet using Deform 2D commercial software The effects of characteristics of the rolling conditions such as roll speed ratio, clad sheet thickness ratio, shear yield stress ratio, roll radius ratio, equivalent roll radius thickness ratio, frictional factor ratio, frictional factor between roll and clad sheet, and reduction ratio etc on the rolling characteristics. The FEM analysis model is compared with various rolling characteristics from the slab method to verify the acceptance of FEM model. The FEM analysis results obtained can be used as the reference of rolling industry. Keywords: Constant Shear Friction, Roll Speed Ratio, Shear Yield Stress Ratio, Frictional Factor Ratio, Reduction Ratio.
