船东对海洋工程船的空船质量要求越来越高,通常船体上层建筑分段选用较薄的板材以降低空船重量及重心,这无疑增加了上层船体分段的建造难度,如何提高上层分段的质量及生产效率,是摆在面前的一个严峻问题。为此需要从生产设计、总段吊环设计及分段预舾装等方面进行优化。 相似文献

AM软件是当今船舶设计中使用最广泛的软件。船体分段套料是船体生产设计的重要环节,套料图是套料工作的重要设计输出之一。为方便船舶建造生产,每个船厂对套料图的格式都有一套自己的规范要求,一般与AM软件输出的格式有出入,这就需要对软件输出进行手工调整,工作量很大。为减轻设计压力,用软件开发手段自动化处理图面成为优先选择。本文对其进行了具体的研究。 相似文献

Methods used for digital ship design were studied and formed the basis of a proposed frame model suitable for ship construction modeling. Based on 3-D modeling software, a digital design system for hull structures was developed. Basic software systems for modeling, modifying, and assembly simulation were developed. The system has good compatibility, and models created by it can be saved in different 3-D file formats, and 2D engineering drawings can be output directly. The model can be modified dynamically, overcoming the necessity of repeated modifications during hull structural design. Through operations such as model construction, intervention inspection, and collision detection, problems can be identified and modified during the hull structural design stage. Technologies for centralized control of the system, database management, and 3-D digital design are integrated into this digital model in the preliminary design stage of shipbuilding. 相似文献

[Objective]To simplify the ship modeling process and improve modeling efficiency, this paper proposes a method for rapidly implementing hull model creation based on hull line drawing.[Methods]Using the CATIA platform, this method adopts the component application architecture (CAA) development tool for secondary development. First, by reading the geometry elements and label information of the hull lines in a drawing, the transformation of the offset points from 2D to 3D is realized. On this basis, the creation of the hull lines, stern and bow is completed, and a 3D wireframe model obtained. Finally, the hull 3D modeling is completed in conjunction with the CATIA native surface creation command. The stability and reliability verification of the developed type value extraction and bow generation program is then carried out via application analysis.[Results]The results show that the compiled program can realize the automatic creation of offset points, transverse lines, waterlines, profile lines and other boundary lines except the top line of the wall, and the centerline and tangent lines created by the bow generator are easily modified and simple for users to operate. [Conclusions]The verification results show that the method of a creating hull model using "Generative Shape Design" and "Drafting" with the hull line drawing as the data input is stable, reliable and able to realize rapid hull modeling, giving it certain practical value. © The Author(s) 2022. 相似文献
