The error analysis system of springback based on dynaform

The flow of numerical simulation for spring back of sheet stamping is first described in this paper. The shortages of analysis method of springback result on CAE soft are expounded. Through researching dynain file, An analysis system of springback error based on dynaform is developed by calling functions from OpenGL graphic library through VC++. The developed system is conducive to subsequent disposal for springback error compensation and die modification.
