Slab Analysis and FEM Simulation on Rotating Compression Forming of Double-Layer Clad Cylinder under Constant Shear Friction

Abstract

The friction caused power losses and bulging deformation are always inevitable. The rotating compression forming can reduce the compression force and bulging deformation in metal forming. Furthermore, the bounded double-layer metal material is able to have advantage in proper material cost saving and meeting the required strength for customer. Accordingly, this present study proposes the analysis based on Slab Method (SM) and Finite Element Method (FEM) under constant shear friction to predict the compression force and the rotating moment in the rotating compression forming. Moreover the bulging deformation profiles, the effective stress, the effective strain, the velocity field, the compression force, the rotating moment, and the twist angle can be obtained from FEM simulations. It is also shown that the predicted results have the same trend to verify the acceptance of analysis models.

“…The effect of the angular velocity of the die on process parameters was emphasized and discussed. Tzou [12] used the SUPERFORM commercial software to explore the compression forming of double-layer bounded clad cylinder, the optimal experimental parameters to affect the uniform of double-layer bounded clad cylinder free surface of double-layer bounded clad cylinder can be obtained. For the optimization of compression forming of double-layer clad cylinder.…”
