Abstract


Sheet metal stamping pressure processing is a widely used method . The forming mold design and manufacturing often rely on the experience of the designer , which led to mold the need for repeated debugging and correction . Simulation technology can achieve the sheet metal forming process simulation , predictive design defects , thereby improving the efficiency of labor , save time , reduce costs . In this paper, elastic-plastic finite element method and LS-DYNA calculation software , numerical simulation model for Wuhan Iron and steel sheet forming process . Steel plate using different parameters and dimensions of the simulation and experimental results are compared to verify the credibility of the calculation models and calculation methods . In this paper, the standard exam to further verify the credibility of the calculation method . This paper quantitatively analyze the influence of relevant parameters on the performance of sheet metal forming stamping , and select the the sump parts finite element model , the stamping simulation and springback calculation , forecasting a possible product defects and the calculation results were analyzed . In this paper, the Visual Basic language and APDL language for secondary development , try to establish the plate stamping process computer-aided analysis system of Wuhan Iron and Steel , Wuhan Iron and laboratory equipment to provide practical numerical simulation analysis platform . The platform provides a practical and friendly operator interface , users only need to enter the appropriate parameters on the numerical simulation of sheet forming process , and can be the result of forming limit diagram need to avoid the cumbersome and complex operation . Finally, an example BHF optimization parameters to optimize the design to provide the appropriate reference data for the experiment , and made ??preparations for the next step in the development of more complex optimization system .
