以ABAQUS软件为平台,建立了能反映内台阶截面环件轧制过程中锻透的三维有限元模型,基于Abaqus/Explicit提供的显式动力学有限元算法,模拟了内台阶截面环件轧制成形过程中塑性变形情况,通过对轧制过程中不同压下量时台阶截面环件轴向不同高度处的等效应变分析,得出了台阶截面环件轧制过程中的锻透规律。对台阶截面环件锻透状况分析及其生产中工艺的制定有一定的指导作用。
On the base of ABAQUS software systen ,the 3D finite element model at the rolling of the ring with steps is established;the plastic deformation in the rolling of step-profile ring is simulsted by explicit dynarmics method in ABAQUS、By analyzing the equivalent strains at the different axial width with different feeding quality in the rolling,the rule of the plastic penetration is obtained.
