The Results Comparasion of Calculation Method and Computer Modeling of Double Curvature Sheet Shells in Stretch Forming Process

Abstract:

In this paper was conducted the dichotomous principle analysis, which based on the results comparability of calculation method and the computer simulation results of forming double curvature sheet shells using new scheme stretch forming and program PAM-stamp. The new scheme involves initially perform shaping the central part of the shell with the press jaws of the straight line. Then press clips installed on the contours, which corresponding with curves of stretch die end sections, and performed extension stretch forming up to a point. The results of the calculation method allows to compare the formation stage and extension stretch forming on the results of computer simulation and quickly find the practical applicability of the new scheme extension stretch forming on modern stretch forming press such as FEL. Key words: extension stretch forming process, double curvature shell, computer simulation results, calculation method, stretch forming press FEL.
