Application of mass scaling in simulation of ring rolling by three-dimensional finite element method

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.
