The Effect of Forming Speed on Cold Roll Forming of the Rocket Frame

摘要

Aiming at the forming speed of sheet metal, this paper discusses the influence of technological parameters on the quality of the rocket frame. Using 3D software SolidWorks to establish the geometric model of the plate and the upper and lower rolls required in the cold roll forming process, and introduced it into the finite element analysis software ANSYS/LS-DYNA to analyze the change of stress and strain of the plate during the forming process. By comparing the stress-strain nephograms of sheet metal at different forming speeds, it can be seen that with the increasing of forming speed, the maximum Mises stress of the sheet is gradually increasing, and the maximum stain of the sheet is gradually decreasing.
