摘　　要：通过ANSYS/LS-DYNA有限元分析软件,对楔横轧轴类件的成型过程进行数值模拟,分析楔横轧轴类件轧制过程的应力应变规律,并对各轴向应力应变进行比较,阐明楔横轧轴类件的变形特征,得到轴类零件轧制过程中轧件内部的应变场、轧件表面变形形状等信息,可为其他零件轧制成形机理及变形规律的研究提供理论依据和参考。The cross wedge rolling of shaft parts is simulated by ANSYS/LS-DYNA finite element software.Based on analyzing,the stress-strain law of wedge rolled shaft during the rolling process and the comparisons along each axial stress-strain were made.The deformation characters of cross wedge rolled shafts were clarified and the internal strain fields and surface deformation status of workpieces in the process of rolling have been established.The results provide a reference and theoretical foundation of formation mechanism and rules of deformation for other type of rolled parts.
