| 摘 要： | 提出了一种由空心坯成形直齿圆柱齿轮的新工艺：预锻分流区-分流终锻，用三维有限元数值模拟软件DEFORM-3D^TM进行了数值模拟研究，得到了锻造载荷-行程曲线以及整个成形过程的应力、应变、速度分布等，并与传统的闭式镦挤工艺模拟的结果进行了比较。分析表明．此工艺与传统的闭式镦挤成形方法相比有诸多优点，为该新工艺的工业化应用奠定了理论基础。

| Abstract: | A new technique to form spur gear from hollow billet was proposed,that is performing divided flow region and then final forging by the relief hole.At the same time,3D-FEM simulation of the whole process is performed using DEFORM-3D TM software.And the lode-stroke curve,effective stress distribution,velocity distribution,and so on,were achieved.And then,these results were compared with those achieved using the conventional closed die forging in the same conditions.The results show that this new technique has many advantages over the conventional one,and gives a theory forndation for practical industry productio. |
