摘要
应用ANSYS/LS-DYNA有限元软件,对楔横轧轴类件进行轧制过程的模拟,分析了精整段轧件不同横截面中心点径向应变和横向应变的交变规律。选取轧制实验模型与有限元分析结果做比较,得到了此变化规律与轧件心部产生破坏之间的关系,为深入研究楔横轧的疏松机理提供了依据。
Through the simulation of the process of cross wedge rolling axis with the help of FEM software ANSYS - DYNA, the alternating rule of radial strain and lateral strain on different cross section of workpiece during finishing stage has been analyzed. Through the comparison between typical rolling experiment models and results of analysis of FEM software, the connection of this alternating rule of strain during finishing stage and the internal rarefaction is known, which provides basis for researching rarefaction mechanism of cross wedge rolling.
