Abstract

The invention provides a ship shell expansion calculation method, device and equipment and a storage medium. The method comprises the following steps of: constructing a dot matrix model of the inner surface of a hull plate by acquiring hull plate part contour data to obtain inner surface three-dimensional scatter data; moving the inner surface three-dimensional scatter data to a neutral layer of the hull plate to construct a spline surface; constructing a reference plane according to the middle position of the spline surface, wherein the reference plane is intersected with the spline surface to obtain a base line; dividing the spline surface into a plurality of deployable curved surfaces according to the curvature on the base line, and carrying out expansion; and obtaining an unfolded profile diagram of the hull plate from the spline surface. The method can be in perfect butt joint with the three-dimensional experience platform, overcomes the deficiency of native functions of the three-dimensional experience platform, and realizes the integration of design, manufacturing and production based on a single digital model.

Description

technical field [0001] The present application relates to the technical field of ship aided design, in particular to a ship shell expansion calculation method, device, equipment and storage medium. Background technique [0002] With the continuous advancement of intelligent shipbuilding, Dassault's 3D experience platform is widely used in the shipbuilding field. However, the 3D experience platform adopts the unfolding method of sheet metal, mainly for thin plates (0.5-2mm), and the unfolding process is mainly based on extension. Ship curved plates are generally medium-thick plates (8-35mm), and the processing technology is generally rolling first and then water-fired processing. When unfolding, not only the extension and shrinkage of the material, but also the unfolding base surface due to the thickness of the plate must be considered. offset. After completing the unfolding of the outer plate, it is necessary to obtain the unfolded baseline, roll bend line and rib position...
