According to the researching actualities in ring rolling, this paper researched deeply the basic law of rolling deformation by simulation using ABAQUS software on the base of ring rolling theory and elastic-plastic kinematics explicit FEM. And the residual stress in cold ring rolling was computed by numerical simulation.The mass scaling measures in finite element simulation of ring rolling were researched.

本文针对环件轧制的研究现状，基于环件轧制理论和弹塑性动力显式有限元法，以ABAQUS有限元分析软件为平台，以数值模拟的方式对环件轧制变形的一些基本规律进行更深入的研究，并对环件冷轧时的残余应力进行数值模拟计算。

The ring is rolled by drive roller and mandrel roller, drive roller offer rotation to make ring rotate continuously and mandrel roller offer line feed to make the ring wall become thinner and thinner. The guide roller ensure the ring rolled comfort, and inspect roller check the rings diameter whether reach the limit dimension.

主动辊提供转动，使环件变形区不断循环周而复始的通过轧辊孔型；芯辊提供直线进给运动，使环件壁厚不断减小以实现环件直径扩大的加工过程；导向辊保证轧制平稳进行，检测辊测量轧制环件尺寸是否达到要求以停止轧制。

From the computed ring spacing of three multi-ring basins on the moon (Orientale, Moscoviense and Serenitatis South), it is shown that the tsunami model can only be applied to the area within the main ring, this agrees with the previous conclusion that the Ⅳ ring marks the end of fluidized region and the crater rim of the excavated basin.
