Novel manufacturing technology of hyperbolic plates for shipbuilding

Abstract

On the basis of the principle of dieless hydrobulging technology, a novel hydrobulging technology for manufacturing hyperbolic plates is proposed. First, a toroidal pipe elbow or a partial toroidal pipe elbow is formed, then the single hydrobulged structure can be cut up into some desired plates. It is proved by experiments and finite element simulation that manufacturing technology of hyperbolic plates adopting integrated hydrobulging forming technology is feasible.
