在船体生产设计中,零件编码系统有着重要的地位。零件编码系统(Numbering system)是一个以数码(英文字母或数字)为代号,对船名、机器设备,乃至分段、部件、元件、零件进行命名的系统。零件编码系统具有逻辑性强,便于记忆等特点,目前已被国内外推行造船生产设计的船厂所接受。电子计算机在造船上的广泛应用,也是采用零件编码系统的重要原因之一。零件编码系统可以用串联排列的形式表达船舶建造的工艺流程,简明易懂,一目了然;还便于造船中各种数据的统计汇总,其优点是多方面的。 相似文献

Dimensional control is one of the most important challenges in the shipbuilding industry.In order to predict assembly dimensional variation in hull flat block construction,a variation stream model based on state space was presented in this paper which can be further applied to accuracy control in shipbuilding.Part accumulative error,locating error,and welding deformation were taken into consideration in this model,and variation propagation mechanisms and the accumulative rule in the assembly process were analyzed.Then,a model was developed to describe the variation propagation throughout the assembly process.Finally,an example of flat block construction from an actual shipyard was given.The result shows that this method is effective and useful. 相似文献

To implement efficient production control, this paper provides a timed colored Petri net (timed CPN) approach to performance modeling, real-timed dispatching and simulation of Panel hull block assembly system (PHBAS). The definition of Petri net is extended to accord with the real-world PHBAS’s organization, and the modeling method for hull flow production is provided in order to simplify modeling program. Using modeling and analyzing method, the dynamic characteristics of the system can be emulated and quantitatively calculated and work control tactics can be optimized. For the double bottom hull block shipbuilding system in a recently built shipyard in China, the simulation model with timed CPN was described and the system parameters and optimal task sequence which has the minimum operation time were obtained for a scheduling case. 相似文献

现代造船的两个一体化 总被引:2,自引:1,他引:1
壳舾涂一体化和设计、生产、管理一体化是现代造船模式的基础和核心。壳舾涂一体化实际上是一种造船各要素的有机整合,也是系统工程的一种应用。设计、生产、管理一体化是指设计、生产和管理这三者不同的信息、能量和物质流动能够有机结合,这是设计思维、建造策略和管理思想的一体化,由此要求设计按照壳舾涂一体化制定工作计划,并为生产的壳舾涂一体造船进行相应的生产技术准备。文章从系统思维的角度探索了两个一体化造船的现状、实践和拓展。 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
