Numerical Simulation on Spinning Forming Process of Automotive Wheel Rim

In this paper, the spinning process of automotive wheel rim is simulated with the finite element software DEFORM-3D. The forming of the automotive wheel rim based on finite element method is completed by the improvement of the spinning process. it can be divided into three different stages: spinning stage, flattening stage and shaping stage. The reference data for technological parameter of spinning process is achieved.The results are useful to the further research of the spinning process of automotive wheel rim.
