3D RIGID-PLASTIC FINTEELEMENT ANALYSIS OF BACKW ARD SPINNING OF CYLINDRICAL WORKPIECE

Ruan Feng;Zhou Zhaoyao ( South China University of Technology) LuYan; WanZheng; Xue Kemmg (Harbin Institute of Technology)  
Backward spinning is analyzed by 3D rigid-plastic FEM.A 3D mechanical model for backward spinning is presented. The distributions are obtained of strain一rate and stress in the con- tact area of the roller and its adjacent area.The results can well intemret the principle of defonnation of backward spinning. The relationship between the roller angle and three components ofspinning force is found out, and the optimum roller angle, when the general spinning foree gets to the minimum value, is calculated. The distributions of defonnation area obtained by FEM agree with the experimental result well.
