3D Finite Element Simulation of Rotary Forging in Spiral Bevel Driven Gear

Shape of spiral bevel driven gear is complex and rotary forging process is also difficult. Based on 3D finite element analysis under isothermal condition,the simulation was employed to examine the rotary forging process in spiral bevel driven gear and metal flow procedure and force-time curve and torque-time curve have been obtained.The comparison for forming force between finite element simulation and experiment shew that it was an effective method and also had a disadvantage to compute the load of rotary forging process by finite element method.Finally some questions have been presented for high-precision finite element simulation of rotary forging process in spiral bevel driven gear.
