Effects of mass scaling on finite element simulation of the cold roll-beating forming process

Abstract

The cold roll-beating forming is a cold plastic forming technology for shaping external teeth of parts. The study aims to improve the simulation efficiency of the cold roll-beating forming process. Based on the principle of the roll-beating forming process, the finite element model of a representative simplified tooth groove forming process was established. Through the simulation results, the forming force and the metal plastic deformation are clearly revealed. Meanwhile, the effect of mass scaling on simulation efficiency and precision are discussed. And the experiments are carried out on a specialized forming equipment. Comparing finite element results with the experimental results, it shows the reasonable selection of mass scaling can effectively improve the simulation efficiency with the certain calculation precision. This study provides a reasonable and efficient finite element model and numerical calculation method for relative researches of cold roll-beating forming technology.
