Finite Element Analysis for Precision Forging Process of United Transfer Driven Parking Gear
Forging process is one of the most basic metal forming processes. In this study a new forging process is applied to fabricate a precision forging product uniting parking and driven gears in order to obtain lightweight and cost effectiveness of an automobile. Since the united product using the precision forging process needs high quality and new manufacturing process, 3D computer simulation by FEM has been used to reduce some trial and errors in experiment and obtain the deformation, strain, stress and load of the workpiece and die. The study has tried to find out an optimal process including preform design putting emphasis on tooth filling by DEFORM-3D, a 3-dimensional rigid-plastic finite element code.
