摘　　要：应用粉末烧结材料广义塑性理论,分析和计算了齿轮粉末锻造成形镦粗、复压的变形力和密度,运用M A R C有限元数值模拟了粉末锻造齿轮的成形过程,讨论了数值模拟和理论计算结果。The calculation and analysis of deformation pressure ,workpiece density for upsetting,repressing of gear powder materials are derived based on the generalized plasticity theory of sintered powder materials, and then the deformation and densification of gear powder materials are simulated by the MARC. The numerical results are compared with those of theoretical study at last.
