Abstract

Metal spinning process has observed significant developments in recent years mostly by using finite element analysis. However, a long time-consuming computation is reported. In this paper, a simplified dynamic finite element model is proposed, which can be 4-time faster than a conventional model. The key configuration is a circular plate, the only deformable part, which is considered static but subjected to centripetal forces due to the constant angular velocity. Accordingly, the mandrel becomes a stationary rigid body. The roller, also rigid body, is the only dynamic part. It rotates around the axis of the mandrel and presses the plate in the axial direction. With this configuration, the explicit time scheme can be performed at a larger mass scaling factor or with larger time steps without losing the accuracy of the results. Descriptions for the conventional model and the proposed model and results comparisons are fully detailed in the paper.
