NUMERICAL-SIMULATION OF DEEP-DRAWING PROCESS

In this pager, both rigid-plastic FEM simulation and experimental meth ods are used to systematically analyze axisymmetric deep-drawing proce ss, summarize material flow law in deep-drawing process. The relation between punch force and drawing depth is measured with transducer and other equipment. Contrasting to the experimental result, it shows that this method is successfully applied to simulate deep-drawing process. The method of dealing with boundary conditions raised in this paper p recisely simulate the material warping in the center and the cavity in the flange, and investigate the influence of friction and other param eters on the limit depth of deep-drawing. Although the program shown i n this paper deals merely with the axisymmetric deep-drawing deformati on, it could be applied to upsetting and forging process either.
