Abstract：

The principle of flexible clamp stretch forming was expounded, and the structural features of flexible clamp stretch forming machine and the moving characteristics of clamp were described. The finite element model of flexible clamp stretch forming was set up based on the analysis software ABAQUS. The numerical simulations of flexible clamp stretch forming process for spherical part were conducted using load force and load displacement, respectively. Further, the outline shape，stretching strain and thickness difference of the spherical parts under two load methods were compared and analyzed. The results show that the forming results under load force and load displacement are roughly in agreement, so both can be used in flexible clamp stretch forming. The forming experiment of spherical parts was carried out on flexible clamp stretch forming machine which results in smooth surface and good shape, and finally verifies the feasibility of flexible clamp stretch forming.
