摘要

The roll forming process is a technique for forming ring with complex cross section, which widely used in the fields of aviation, aerospace and other high technology industries. To predict and control the roll forming quality, a 3D elastic-plastic finite element (FE) model of ring with complex cross section for roll forming was developed using the explicit code ABAQUS/Explicit. During the modeling process, several key techniques are solved, such as materials modeling, geometry modeling and grid optimal design. Then the reliability of the model was verified. Furthermore, numerical simulation and analysis of the roll forming process of ring with complex cross section have been carried out by using the model. The distribution regularities of equivalent strain in the process have been analyzed. The results show that with the progressing of roll forming, the equivalent strain increase sharply in the initial stage, then slightly varies, and the W shape of ring cross section is produced gradually.
