Abstract：

The factors influencing on the accuracy of springback calculation,including average mesh size,punch velocity and usage of adaptive mesh refinement,and the factors influencing on springback in sheet forming process,including blankholder force,material properties and friction coefficient,are studied with PAMSTAMP softwere in this paper.
