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 a jig frame intelligent layout method for ship sectional construction and computer storage medium. The jig frame intelligent layout method comprises the following steps that (1) body mass of a ship body curved surface sectional member based on a bounding box algorithm is acquired; (2) surface quality of the ship body sectional member on a projection plane is acquired basedon equal area; (3) point position layout of a jig frame is determined based on constraint conditions such as surface mass, the center of mass of a ship body sectional projection plane and the supporting weight of a single jig frame; (4) a mathematical fitting model of a ship sectional outer plate on the point position and height of the jig frame is acquired; (5) a contact point position between the jig frame and the sectional outer plate is determined; (6) a supporting point position of an uppermost pillar of the jig frame is determined; and (7) the rising height of a lead screw is determined.According to the jig frame intelligent layout method for the ship sectional construction, the accuracy and a utilization rate of the jig frame layout are effectively improved, an intelligent level ofthe jig frame layout is improved, the accuracy, the quality and the production efficiency of the ship body sectional member are improved, and the labor intensity of workers is reduced; and the jig frame intelligent layout method is first proposed in the field of ship construction at present, and has wide development space.

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, ...
