Press forming result prediction data adjustment system and program, and impact analysis system

摘要

Data for an initial condition in impact analysis is efficiently obtained by performing adjustment to bring the press forming result prediction data closer to the actual press forming result. A component data storage unit for storing component data including histogram data relating to plate thickness change rate or plastic strain for each component, similar component data including histogram data of similar components, and plate thickness change rate of target components. Alternatively, the data acquisition unit 100 that acquires target part data including press molding result prediction data relating to plastic strain, the target part histogram data generation part 230 that generates histogram data of the target part, and the histogram data of similar parts and target parts are the most. Similarly, a plate thickness change rate adjustment amount determination unit 240 and a plastic strain adjustment amount determination unit 250 that determine the plate thickness change rate or plastic strain adjustment amount of each element of the target part, and press molding based on the adjustment amount A press forming result prediction data adjustment unit 260 that adjusts the result prediction data.
