Abstract :
Rigid-viscoplastic finite element method is used to analyze precision forming process of the speed-reducer shaft of auto starter. And the varying rules of extruding forces, velocity, stress, strain as well as metal fluent regulation were obtained. The forming defects occurring in practice were predicted well. This research plays a guiding role on the simulation of the cold forging and the design of the die set.
