Abstract：

Through a deep study on the basic theory of fast calculation, its simplification and hypothesis of process and calculation, application conditions of the calculation method were offered, namely the linear conditions of strain path. Most of the parts from bending, stamping, flanging and simply drawing in the automobile met the above conditions. For flange structure of extension category which the most enough met the linear loading condition,had the least simplification and hypothesis,and the most problems occured in product design, fast calculation result and parameter determination were tested and calibrated by accurate calculation. As a result, the criteria and special attentions of the above calculation method were confirmed. By comparing the calculated results, their deviation is less than 10%, and the assessment of stretch flanging structure technology is feasible by fast calculation.
