Abstract

The present invention discloses a rapid mesh division method for a hexagonal integrated multi-opening superstructure of a ship. The method comprises: establishing a geometric shape model for the hexagonal integrated multi-opening superstructure of the ship at first; and then, by cutting each plane, and taking an obtained straight line after cutting the plane as a geometric model of an aggregate structure, simultaneously dividing the obtained straight lines and the planes after cutting into finite element meshes, thereby obtaining a mesh model for the hexagonal integrated multi-opening superstructure of the ship. According to the method disclosed by the present invention, finite element mesh models with different geometric sizes of the superstructure outlines, different number of openings, different opening sizes, and different opening positions can be rapidly obtained, so as to improve the mesh division speed of the hexagonal integrated multi-opening superstructure of the ship, facilitate rapid mesh division of various design schemes with different parameters in a short time, and improve analysis efficiency.

Description

technical field [0001] The invention is applicable to the fast grid division of the hexagonal integrated multi-opening ship superstructure, and is used for parametrically generating a geometric model under different design parameters, and quickly dividing the finite element grid. Specifically, it involves the parametric generation geometric model of the hexagonal integrated multi-opening ship superstructure and the parametric finite element mesh division of the multi-opening stiffened plate geometric model. Background technique [0002] Since stealth technology can effectively reduce the detectability of surface ships and significantly improve the anti-strike capability, it has increasingly received great attention from navies of various countries. The superstructure of a ship is located above the water surface, and its stealth characteristics largely determine the survivability of the entire ship. In the 21st century, the superstructure of ships is developing towards integ...
