考虑工程约束的造船精度分析与搭载算法研究

In order to improve the efficiency and quality of shipbuilding, shipbuilding mode is to develop in the direction of giant section construction. How to rapidly and accurately analyze the errors between the product and the theoretical model during the construction of the hull block to improve the efficiency of blocks assembly has become a hotspot in global ship engineering research field. The current matching methods neglect the engineering constraints thus can not meet the practical engineering demands, resulting in some problems, such as low efficiency of blocks assembly. This project focuses on shipbuilding accuracy control key technologies, including accuracy analysis method with engineering constraints, intelligent generation of blocks assembly plans, quick erection and assembly method based on multi-DOF adjustable platform, etc. Accuracy analysis algorithm and assembly algorithm with engineering constraints are proposed. This study aims to solve the problem of actual points (-measured by total station in domestic shipyard-) and theoretical points registration and accuracy comparing analysis enhance provides a decision basis for non-margin assembly, shorten blocks assembly locating period, dispense reliance on gantry crane, extend the ground operation period, save energy of gantry crane and labor costs.

为了提高造船效率和质量，造船模式正在向总段巨型化建造工艺方向发展，如何快速准确地分析建造过程中船体分段产品与理论模型之间的误差，以及如何提高分段搭载效率，已经成为国内外船舶工程领域研究的热点。本项目针对目前船体分段测量数据分析算法不考虑船舶工程约束，得出的分析结果往往不符合工程实际要求，严重影响后续分段搭载效率等问题，对考虑工程约束造船精度分析方法、分段搭载方案智能生成方法和基于多自由度可调平台的分段快速搭载合拢对位方法等造船精度控制相关关键技术进行研究，并提出考虑工程约束的造船精度分析与搭载算法。本研究旨在解决目前国内各船厂应用全站仪测得的分段实测点与理论点匹配及精度分析对比问题，为无余量搭载提供决策依据；缩短分段搭载定位工期，解放对龙门吊机的依赖，扩大地面阶段作业面，节约龙门吊能耗和搭载人力成本。
