中文摘要：
利用三维有限元软件DEFORM-3D,在变形瞬间状态及力学量场可视化环境下,模拟了3种相同体积的毛坯形状成形时对填充质量的影响,得到了摆辗载荷-时间曲线以及成形过程的变形速度分布图。数值模拟分析结果表明：采用圆鼓毛坯时齿轮充填性良好;锥形毛坯中部局部＂缺肉＂;圆柱毛坯的充填质量与锥形毛坯的充填质量相似,但稍好些。这对摆辗工艺的合理制订具有一定的理论意义。
英文摘要：
The deformation process was simulated with finite element method software-DEFORM-3D under the circumstance of instantaneous state of deformation and visual mechanical environment. The regularity of metal flow, load-time curve, and velocity-z/Theta fields were obtained. The simulation results show that filling condition is ideal when the blank is drum shape, and the defects will happen when using the cone and cylinder blank So the simulation results of the rotary forging can provide theory basis for the industrial production.
