Abstract
ANSYS/LSDYNA is applied to simulate the sheet forming process and the springback distortion process. The springback result of sheet and stress, strain in process will be obtained. The influencing factor to the springback includes bank holder force, sheet thickness, velocity of punch, and cutting tool radius in process. The springback law can be used to compensate the mould design. Therefore, the structural parameters of the fin forming machine and the process parameters of relative mould device will be optimized. Then the accuracy of offset strip fin will be improved , it will provide a reliable basis for the Fin structure optimization design.
