【摘要】 通过有限元Ansys/Ls-Dyna分析软件,对特大型轴类件和小轴类件分别进行楔横轧数值模拟,分析特大型轴类件的应力应变规律,并与小轴类件比较,阐明楔横轧特大型轴类件变形特征研究,为合理选择模具工艺参数,实现特大型轴类件楔横轧精确成形提供重要的理论依据。更多还原

【Abstract】 By using Finite Element Method Ansys/Ls-Dyna software,digital simulation for oversize axes and small axes during cross wedge rolling,analysis orderliness of stress and strain of oversize axes,compared to small axes, clarify study on deformation character of oversize axes during cross wedge rolling,The result provides important theoret- ical basis for logical select die of technical parameter and achieving accurate forming of extra-large axes.更多还原
