Abstract

A new stretch forming process based on distributed displacement loading for three-dimensional surface parts is proposed, the external stretching displacement load is applied at a series of discrete points, so the flexibility of the loading mechanism is improved. The forming process can be realized by controlling the loading trajectory at each discrete point and the formed part with the thickness uniformly distributed are obtained. In order to investigate the influence of the loading time-steps on the forming results in the in the process of stretch forming three-dimensional surface part based on distributed displacement loading, the forming process with three different time-steps were numerical analyzed. By analyzing the numerical results, it can be concluded that the more loading time-steps is, the smaller the shape error will be stretch forming three-dimensional surface part based on distributed displacement loading.
