摘要

本研究以SUPERFORM商用分析軟體進行雙層複合圓環旋轉壓縮成形之有限元素模擬，模具與雙層複合圓環之間的摩擦假設為定剪摩擦，上下摩擦可假設不同。雙層複合圓環壓縮成形的內外表面形狀、等效應力、等效應變、速度場、壓力分佈、壓縮負荷及旋轉力矩可由有限元素模擬。並探討複合圓柱高度比、摩擦因子比、旋轉角速度等壓縮條件對於壓縮特性求得之影響。

This study carries out an FEM simulation on rotating compression forming of double-layers clad ring by SUPERFORM commercial analysis software. Frictions between the upper and lower dies and the double-layers clad ring are assumed as constant shear frictions, but can be different. The shape of the inner and outer surfaces of the double-layers clad ring, the equivalent stress, the equivalent strain, the velocity field, the compression distribution, the compression force, and rotating moment can be determined from the FEM simulation. Effects of various compression conditions such as the clad cylinder height ratio, the frictional factor, the rotating angular velocity etc on the compression characteristics are explored in this study.
