【摘要】：超短基線定位技術(shù)目前普遍應(yīng)用于海洋開(kāi)發(fā)、探測(cè)等方面，，是一種水下定位探測(cè)技術(shù)，主要功能是：確定水下遙控機(jī)器人(remotely operated vehicle,ROV)、水下無(wú)人機(jī)器人(unmanned underwater vehicles, UUV)、水下自動(dòng)機(jī)器人(autonomous underwater vehicle, AUV)、聲納設(shè)備的水下拖魚(yú)(tow fish)、潛水員以及水下其他載體的精確位置。而作為超短基線定位系統(tǒng)的重要組成部分，超短基線升降裝置能夠?qū)Q能器精確地定位到水下某位置，直接影響超短基線定位系統(tǒng)的可靠性和測(cè)量精度。 經(jīng)過(guò)考察研究現(xiàn)有船舶和設(shè)備，我們提出了升降裝置的設(shè)計(jì)結(jié)構(gòu)并在“大洋一號(hào)”上成功安裝，取得了良好的成果。鑒于此超短基線升降裝置的良好表現(xiàn)，“向陽(yáng)紅九號(hào)”也將安裝一套同樣的升降裝置。本文主要是針對(duì)第一臺(tái)設(shè)備在測(cè)試和安裝過(guò)程中出現(xiàn)的問(wèn)題進(jìn)行了分析改進(jìn)，并重新設(shè)計(jì)加工，完成的新設(shè)備即將在“向陽(yáng)紅九號(hào)”上安裝。同時(shí)為了縮短設(shè)備的研發(fā)周期，節(jié)約成本，提出了一種超短基線升降裝置的裝配序列優(yōu)化方法，能夠高效快速地進(jìn)行設(shè)備的裝配。最后本文通過(guò)有限元軟件ANSYS workbench對(duì)設(shè)備進(jìn)行了模態(tài)和諧響應(yīng)分析，分析結(jié)果和試驗(yàn)測(cè)試結(jié)果互相驗(yàn)證，各零部件的尺寸規(guī)格符合設(shè)計(jì)要求，裝置運(yùn)行平穩(wěn)性和精度滿足技術(shù)要求。 本文兩大創(chuàng)新點(diǎn)：一個(gè)是提出一種新型閥門(mén)遠(yuǎn)程控制方案，另一個(gè)是提出一種針對(duì)該裝置的裝配序列優(yōu)化方案。新型閥門(mén)遠(yuǎn)程控制方案，動(dòng)力傳遞安全可靠,故障率低,成本低,維修方便,保證了操作人員的人身安全。同時(shí)閥門(mén)遠(yuǎn)程控制裝置操作安全，靈活簡(jiǎn)便，可以有較多的推廣應(yīng)用。裝配序列優(yōu)化方案是采用層次聯(lián)接關(guān)系圖對(duì)超短基線總裝及其部分零部件的總裝進(jìn)行裝配建模，然后用層次化割集法生成超短基線及其零部件的裝配序列，接著通過(guò)討論裝配序列的操作并行性、穩(wěn)定性、重復(fù)定向性及聚合性來(lái)評(píng)價(jià)超短基線及其部分零部件的裝配序列，得出最優(yōu)的裝配序列。
[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.
