Optimization Design for the Forming Process of Car Side Door

Based on the CAE analysis technology, possible defects of the sheets in the forming process are accurately simulated and predicted, and the method of eliminating defect is found. The results of the analysis not only improve the work efficiency, shorten the design and manufacturing cycle of the mold, but also provide a strong support for the design of mold and the development of the technology program. At the same time, the calculation results are consistent with the actual situation by using Dynaform software to simulate the results. The accuracy and the reliability of the calculation results by using the numerical simulation technology is validated.
