【摘要】：超短基线定位技术目前普遍应用于海洋开发、探测等方面，，是一种水下定位探测技术，主要功能是：确定水下遥控机器人(remotely operated vehicle,ROV)、水下无人机器人(unmanned underwater vehicles, UUV)、水下自动机器人(autonomous underwater vehicle, AUV)、声纳设备的水下拖鱼(tow fish)、潜水员以及水下其他载体的精确位置。而作为超短基线定位系统的重要组成部分，超短基线升降装置能够将换能器精确地定位到水下某位置，直接影响超短基线定位系统的可靠性和测量精度。经过考察研究现有船舶和设备，我们提出了升降装置的设计结构并在“大洋一号”上成功安装，取得了良好的成果。鉴于此超短基线升降装置的良好表现，“向阳红九号”也将安装一套同样的升降装置。本文主要是针对第一台设备在测试和安装过程中出现的问题进行了分析改进，并重新设计加工，完成的新设备即将在“向阳红九号”上安装。同时为了缩短设备的研发周期，节约成本，提出了一种超短基线升降装置的装配序列优化方法，能够高效快速地进行设备的装配。最后本文通过有限元软件ANSYS workbench对设备进行了模态和谐响应分析，分析结果和试验测试结果互相验证，各零部件的尺寸规格符合设计要求，装置运行平稳性和精度满足技术要求。本文两大创新点：一个是提出一种新型阀门远程控制方案，另一个是提出一种针对该装置的装配序列优化方案。新型阀门远程控制方案，动力传递安全可靠,故障率低,成本低,维修方便,保证了操作人员的人身安全。同时阀门远程控制装置操作安全，灵活简便，可以有较多的推广应用。装配序列优化方案是采用层次联接关系图对超短基线总装及其部分零部件的总装进行装配建模，然后用层次化割集法生成超短基线及其零部件的装配序列，接着通过讨论装配序列的操作并行性、稳定性、重复定向性及聚合性来评价超短基线及其部分零部件的装配序列，得出最优的装配序列。
[Abstract]:At present, ultrashort baseline positioning technology is widely used in marine development, exploration and other aspects. It is a kind of underwater positioning and detection technology. The main functions are: to determine the exact position of underwater remote control vehicle (remotely operated vehicle), underwater unmanned vehicle (unmanned underwater vehicles,), underwater automatic vehicle (autonomous underwater vehicle,), underwater towing (tow fish), diver of sonar equipment and other underwater vehicles. As an important part of ultrashort baseline positioning system, ultrashort baseline lifting device can accurately locate the transducer to a certain position under water, which directly affects the reliability and measurement accuracy of ultrashort baseline positioning system. After investigating and studying the existing ship and equipment, we put forward the design structure of the lifting device and successfully installed it on "Yangyang No. 1", and obtained good results. In view of the excellent performance of this ultrashort baseline lifter, Xiangyang Red 9 will be fitted with the same lifting gear. In this paper, the problems in the test and installation of the first equipment are analyzed and improved, and the new equipment is redesigned and processed. The new equipment will be installed on Xiangyang Hong No. 9. At the same time, in order to shorten the research and development cycle of the equipment and save the cost, a method of assembly sequence optimization of the ultra-short baseline lifting device is proposed, which can efficiently and quickly assemble the equipment. Finally, the modal harmonious response of the equipment is analyzed by the finite element software ANSYS workbench. The results of analysis and test verify each other. The dimensions and specifications of each component meet the design requirements, and the running stability and precision of the device meet the technical requirements. There are two innovations in this paper: one is to propose a new valve remote control scheme, the other is to propose an assembly sequence optimization scheme for the device. The new valve remote control scheme is safe and reliable in power transmission, low in failure rate, low in cost and convenient in maintenance, thus ensuring the personal safety of the operator. At the same time, the valve remote control device operates safely, flexible and simple, and can be popularized and applied. The assembly sequence optimization scheme is to model the assembly of the ultra-short baseline assembly and parts by using the hierarchical connection relation diagram, and then generate the assembly sequence of the ultra-short baseline and its parts by using the hierarchical cut set method. Then, by discussing the operation parallelism, stability, repeatability and polymerization of assembly sequence, the assembly sequence of ultra-short baseline and some parts is evaluated, and the optimal assembly sequence is obtained.
