摘　　要：利用Solidworks三维造型软件对圆柱直齿轮进行参数化建模;采用正挤压成形工艺,使用有限元数值模拟软件Deform-3D对冷锻成形过程进行三维刚塑性有限元数值模拟;确定了合适的齿根圆角半径以优化成形工艺,为实际生产提供参考。The parametrical modeling of column spur gear was set up by software Solidworks;adopting forward extrusion forming process,and using finite element simulation software Deform-3D,the cold forging forming of the gear was simulated;then the suitable dedendum fillet radius was defined to optimize forming process,which can give a reference for practical production.
