Abstract：

In order to reflect the real friction coefficient in the process of forming exactly and develop a real-time measure system of forming,the geometry parameters, such as punch profile radius,the arch rise and radius of curvature,the draw bead profile radius etc.were changed and the displacement in the process of stamping and bulging were analyzed by the finite element software.The curves of the displacement and other parameters were found,by which the punch surface would be optimized and the installed positions of the combined specificity sensor were confirmed.It would be the directive gist for founding the real-time measure system for friction coefficient of sheet metal forming.
