Study On Simulation Of Stamping Process Of HFC6500's Rightbracket

Automobile panels are the parts of the most difficult forming in sheet metal forming domain, for it has a series of strongpoint such as high productivity, steady quality, lower cost, feasibility of processing complicated shape etc. However, the design of stamping die was mainly depended on the designer's experience. The quality of designing is hardly steady for some complicated forming. Some important parameters can be confirmed only after the die had been produced and then been repaired for many times. Time and resource are wasted by this way. With the development of finite element technique and computer, numerical simulation has become the effective tool of technology analysis and optimal design step by step.The application of computer and computer-aided technology in the areas of blank shaping is increasingly the same wide and deep as other objects. In this thesis, we study the finite element simulation of automobile panel in detail. Numerical simulations and experimental research are carried out in the process of automobile panel drawing.On the basis of material mechanical test and forming limit analysis, the simulating results and experimental stamping results are compared by grid strain analysis technique, The validity of modeling, the accuracy and reliability of simulation results for stamping forming processes of rightbracket are validated. Both the simulating and experimental stamping predict that the strain distributions are sharply concentrated in several corner areas, local areas are close to crack. In the face of this situation, the improving processes are proposed based on the Theoretical Forming Limit Diagram analysis.
