The flow forming process simulated by finite element method
In spinning process of automotive drive housing part with spline, the billet is shaped by rolling depression using three rollers, the part material is formed by three rollers to expand and squeezed and then it is shaped. Using finite element method, the spline shaping process of the part is simulated. After simulation, it can be seen that the interior of the part presents three-way compression stress and rim of the interior the local principal stretch. At the same time the spline shaping process is simulated by the finite element method, it can be learned that partial part material flows forward, and the other material flows backward. When the feed rate of roller is high, main tendency is material flowing forward, whereas other material flows backward. While, when the feed rate of roller is low, main tendency is material flowing backward. Finally, simulation results of flow forming taken with different parameters are discussed. Furthermore, by comparing simulation results with test results, it can be learned that they are basically in agreement. Therefore, the simulation example demonstrates the efficiency of finite element methods used in spinning process of part.
