Abstract
Abstract
The finite element simulation of the roll forming process of the container roof is carried out, and the stress, strain, and history curves of key nodes are analyzed. It is proved that the rolling process will produce edge wave and wrinkle defects in the flat section, and the influence of parameters on the edge wave wrinkle is studied. Studies have shown that: the length of the transition section increases, the number of wrinkle decreases; the distance between the arches increases, which suppresses the generation of side wave defects, but after more than 350mm, the effect on the side wave remains unchanged; the width of the sheet edge increases, and the side wave defects follow the increase.
