Abstract:
The rolling forming process of automobile variable cross-section longitudinal beam is more complex than the traditional constant cross-section roll forming. In the forming process, there will be not only common defects of traditional rolling forming such as thinning, edge wave, wrinkling, springback and distortion, but also unique instability and wrinkling defects caused by cross-section change. In view of the above forming defects, this paper puts forward three quality evaluation indexes: the change rate of wall thickness to evaluate the change of wall thickness, the instability degree of side wave phenomenon, and the maximum bending angle and spring back angle to evaluate the bending or spring back degree of longitudinal beam. In this paper, the quality evaluation and influencing factors of rolling forming of variable section longitudinal beam are studied by means of ABAQUS finite element software. In order to reduce the workload of finite element modeling, this paper establishes the correct finite element model and three-dimensional model by means of orthogonal test. By analyzing the main factors affecting the forming quality of automobile variable section longitudinal beam, it provides a certain reference for the rolling production development of variable section longitudinal beam.
