摘要
从动螺旋伞齿轮的形状复杂,摆动辗压难度大。采用刚粘塑性有限元对从动螺旋伞齿轮摆动辗压工艺进行了模拟,获得了从动螺旋伞齿轮的摆动辗压变形规律和力能曲线。通过对辗压力模拟计算与实验结果的比较,阐释了有限元模拟计算辗压力的有效性和不足。最后指出了对螺旋伞齿轮进行高精度的计算模拟要考虑的问题。
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.
