| 摘 要： | 利用MSC.Marc大变形有限元仿真软件进行轧制过程数值模拟;通过X、Y方向位移云图切片技术分析金属流动规律,并用横向切片轮廓节点的"时间位移"图对变形过程进行细化分析,获得轧制后钢轨的轨高、头宽、腰厚及底宽等钢轨断面关键尺寸信息;通过Z方向位移分析优化延伸率的分配。结果表明:用该方法对依靠经验设计的重轨万能轧制孔型进行优化,缩短了产品孔型开发时间,节约了孔型开发成本,提高了产品轧制精度。

| Abstract: | The heavy-rail rolling process is simulated with MSC.Marc software.The flowing law of metal by slicing the nephogram of X,Y direction displacement is analyzed.Then the course of deforming by "time-displacement" chart of nodes on the outline of horizontal slice is particularly studied.The distribution of the coefficient of elongation is optimized through analyzing Z direction displacement.The result shows that utilizing this method to optimize the universal rolling pass which designed by experience can save ... |
