Variable cross-section roll forming is a new process developed on the basis of traditional constant forming. It can produce variable products flexibly and efficiently, which great significance to automobile lightweight. In this paper, rolling section longitudinal beam simulated, finite element model sheet metal established in ABAQUS software, deformation stress distribution are analyzed. conclu...

Development of computer technology offers ever more elaborated and some novel mathematical modeling methods for description of materials response to rolling. Research in this field has been undertaken by a number of experts who proposed numerous particular models 1-7 . Using these models can provide detailed information on changes in thermomechanical variables during rolling and enable the pred...

Abstract The uniform thickness hollow axle is one of the lightest weight axles in high-speed rail industry. It can effectively reduce unsprung mass and further improve train speed. Therefore, due to its importance significance, it crucial research develop axle. To understand microstructural evolution during three-roll skew-rolling (TRSR) forming, 30CrMoA alloy steel was used this study. A const...
