Stamping analytical method

The present invention relates to a press forming analysis method, which has a press forming analysis step, analysis step and resilience shape analyzing step. In the press forming analysis step for press molding is heated to set the initial temperature distribution of the material, structural analysis and temperature analysis and a combination press-molded parsing shape information acquired before release after press molding, the temperature distribution , stress distribution and strain distribution. In the springback analysis step, based on the shape information obtained press forming analysis step, temperature distribution and stress distribution and strain distribution, so the temperature analysis and structural analysis combination springback resolved, the shape information obtaining springback , temperature distribution and stress distribution and strain distribution. In the shape analyzing step, on the basis of the shape information acquired springback analysis step, the temperature distribution and stress distribution and strain distribution, so the temperature analysis and structural analysis, parsing combination until the temperature of the above-described press-molding material distribution becomes ± 5 ℃ cooling within the shape change and after cooling.
