Abstract

The invention provides a through hole design method and system based on design rules, and the method comprises the steps: building a through hole parameter template library according to a through holestandard node graph; selecting plates and profiles, obtaining plate information and profile information, and automatically matching the type of the through holes; according to the profile and plate information, generating through holes, supplementary plate contours and thickness information in batches; according to non-standard special requirements, defining parameters such as intervals and the like, and completing contour definition of the through holes and the supplementary plates. The method has the beneficial effects that the workload of creating the through hole parameter template library by a designer is reduced; manual selection of through hole types and manual definition of parameters by designers according to a standard node graph are reduced, the design difficulty is reduced, and the design efficiency and accuracy are improved; and the development of knowledge engineering and digital design is promoted.

Description

technical field [0001] The present application relates to the technical field of ship hull structure design, in particular to a method and system for designing through-holes based on design rules. Background technique [0002] With the rapid development of digital design technology in the shipbuilding industry, digital design technology based on 3D models has been widely used in the shipbuilding field. In the hull structure, in order to ensure the continuity of the longitudinal profiles of the hull and meet the structural strength requirements, it is necessary to design profile through holes. However, due to the diversification of the intersection forms of the profile and the plate (especially the non-orthogonal case), the outline design of the through hole is cumbersome. On the one hand, in order to meet all the geometric scenarios where profiles and plates intersect, the designer of the basic library needs to define individual parameters for each type according to the sta...
