Embodiment Construction

[0033] The present invention maps the three-dimensional model to the plane to determine the mass distribution on the plane, based on the mass distribution of the components on the plane and the slope of the hull section and other related constraints, determines the number of tire frames required, and according to the position of the center of mass of the hull section And the mathematical fitting model of the hull segment determines the point arrangement of each tire frame and the rising height of the screw. The specific process is as follows: figure 1 shown.

[0034] In the first step, each component is coded one by one according to the coding rules, and the component type f and the quantity k of various components on the hull surface segment are judged according to the material code in the BOM table.

[0035] The second step is to use the bounding box algorithm to construct the minimum bounding box of each component. Its method is as figure 2 As shown, first determine the ...

Abstract

The invention discloses an intelligent tire frame layout method and computer storage medium for the segmental construction of ships. The method includes the following steps: 1) acquiring the body weight of segmented components on the curved surface of the hull based on the bounding box algorithm; 2) acquiring the hull based on the equal area The surface mass of the segmented member on the projection plane; 3) Determine the point layout of the tire frame based on the surface quality, the centroid of the hull segmented projection plane, and the supporting weight of a single tire frame; 4) Obtain the ship’s segmented outer plate Mathematical fitting model about the position and height of tire frame; 5) determine the contact point between tire frame and segmented outer plate; 6) determine the support point of the uppermost pillar of tire frame; 7) determine the rising height of screw. The present invention effectively improves the accuracy and utilization rate of tire frame layout, improves the intelligence level of tire frame layout, improves the accuracy, quality and production efficiency of hull segmental construction, and reduces the labor intensity of workers. It is proposed for the first time and has a broad space for development.

Description

technical field [0001] The invention relates to an intelligent tire frame layout method and a computer storage medium, in particular to an intelligent tire frame layout method and a computer storage medium oriented to ship segmental construction. Background technique [0002] Ship segmented components are sections formed by rationally dividing the hull according to the structural characteristics of the hull and the requirements of the construction process. In product production design, according to the principle of segmented construction and the actual situation of production facilities, the main basis is that the workload of each segment is similar, and the hull segments are divided scientifically and reasonably, so that the design of intermediate products is reasonable, and each segment The production workload is balanced. During the construction process of each section, multiple tire frames are needed for support. In order to improve the efficiency of tire frame layout, ...
