Rear View Mirror Mounting Plate Numerical Simulation Of Forming

Sheet metal stamping is the application of a wide range of material processing method. however, the deformation of the forming process is a complex process of multi-body contact mechanics, it's a very typical of nonlinear problems. So, engineers can not accurately determine whether the product is wrinkling, fracture and springback in pre-production, the quality of sheet metal forming part rely on the experience of engineers.Dynaform is a professional software in sheet metal forming simulation. It is a collection of its own pre-streamlined, LS-DYNA960, strong analytical ability of LS-DYNA970 and eta-Post post-processing, the analysis engine used the world's leading LS-NIKE3D solver and the solver LS-DYNA. Because of the finite element simulation technology can save costs, improve efficiency and Sophisticated software technology. Dynaform widely be used in major enterprises, universities and research institutes Currently.This article is research about the rear view mirror mounting plate which will be produced by factory, analysis the product designed by engineers, predict possible defects, examin the design is reasonable. Don't modifying the mold surface and choose the drawbead rectangle, increase the height of rectangle drawbead, increases the force of blank holder after discover defects, but the effect is not obvious finally. Therefore, by use of modify the mold surface,choose the drawbead rectangle, increase the height of rectangle drawbead, increases the force of blank holder.,the defects be solved.Rear view mirror mounting plate on Dynaform forming simulation a significant effect on production. It is not only timely detection of defects which engineers suspected the area, and predicted the defects which engineers would not find. Dynaform forming simulation reduce the factory test mode, save a few million of funds for factory, and reduce production costs effectual.
