Multi-point Digitalization Research of Hull Plate Based on Visual Communication of Hull Information

The surface of hull plate is mostly composed of complex and inextensible spatial surface. The bending process of it is still finished by hand, which has become one of the bottlenecks in the digitalization of hull construction. In order to realize the digital processing of hull plate, combined with visual communication and according to the requirements of hull plate forming technology, a technical scheme based on PID control method was applied to the hull plate forming. By applying the multi-point forming process, large-scale steel plate was formed in the small equipment. In the multi-point digital forming system, combined with the PID control method, the required shape was obtained through precise position control of the multiple basic bodies of the hull plate. The experimental results show that the multi-point forming technology can better finish the digital forming of hull plate, and it can be used for hull plate forming process after accuracy testing.
