阐述了三维有限元法模拟环件轧制过程中采用质量缩放方法的意义和理论依据，对显式动态有限元过程模拟中的质量缩放方法进行了分类，得出了环件轧制过程中质量缩放方法的选择原则。最后，基于ABAQUS/ EXPLICT操作平台，建立了环件轧制过程的刚塑性有限元铅模型，通过模拟计算和计算理论的比较，验证了选取的结果，从而总结出最合适的环件轧制质量换算方法。
The significance and theoretical basis of using the method of mass scaling in the simulation of ring rolling by the three-dimensional finite element method was elaborated in this paper,and the methods of mass scaling were classified in the process simulation of explicit dynamic finite element,and the principles of selecting the method of mass scaling were gained in the process of ring rolling. In the end,the rigid-plastic finite element plumbum modeling was established on the base of ABAQUS/ EXPLICT operating flat.The selecting result was proved through simulation and comparing the calculation theory.Consequently,the most appropriate ring rolling mass scaling method was summarized.
