【摘要】：深海測(cè)試平臺(tái)是在布放在深海海底，對(duì)深海海洋動(dòng)力環(huán)境、化學(xué)環(huán)境、地球物理環(huán)境進(jìn)行長(zhǎng)時(shí)間實(shí)時(shí)監(jiān)測(cè)，并將監(jiān)測(cè)數(shù)據(jù)通過(guò)主接駁盒、次接駁盒和光纜實(shí)時(shí)傳輸至海岸基站的測(cè)試系統(tǒng)。深海測(cè)試平臺(tái)的想法最初產(chǎn)生于冷戰(zhàn)時(shí)期的美國(guó)軍方，其目的是海底水聲監(jiān)視，主要是監(jiān)視其他國(guó)家的艦艇。如今深海測(cè)試平臺(tái)的用途和功能更為寬泛，可以為深海生態(tài)系統(tǒng)的研究提供更多更可靠的實(shí)時(shí)數(shù)據(jù)，，為海洋對(duì)氣候的影響的研究給予支持，可以實(shí)時(shí)進(jìn)行海洋監(jiān)測(cè)，為海底地震引起的海嘯等災(zāi)害提供預(yù)警等。人類(lèi)對(duì)深海海底的探測(cè)尚處于起步階段，深海測(cè)試平臺(tái)的設(shè)計(jì)也處于初步探索階段，本課題的實(shí)施對(duì)我國(guó)海洋探測(cè)的發(fā)展起到一定的推動(dòng)作用。 本課題與國(guó)家海洋局第二海洋研究所合作，目的在于設(shè)計(jì)能夠滿(mǎn)足使用要求的深海測(cè)試平臺(tái)機(jī)構(gòu)，并分析優(yōu)化整個(gè)平臺(tái)自由下沉和設(shè)備釋放時(shí)的穩(wěn)定性，主要完成如下設(shè)計(jì)工作： 1）按照項(xiàng)目組要求，設(shè)計(jì)尺寸大小合適，結(jié)構(gòu)外形合理，便于長(zhǎng)途運(yùn)輸，能搭載兩個(gè)地震儀、一個(gè)磁力儀、一個(gè)控制倉(cāng)、一個(gè)電池倉(cāng)，以及相關(guān)電纜與零配件和的深海測(cè)試平臺(tái)。 2）建立深海測(cè)試平臺(tái)及其相關(guān)機(jī)構(gòu)的三維數(shù)據(jù)模型，使用流體分析軟件，分析整個(gè)平臺(tái)在水中自由下降過(guò)程中的受力情況和穩(wěn)定性，并根據(jù)分析結(jié)果優(yōu)化外形設(shè)計(jì)、儀器的安裝位置等。 3）設(shè)計(jì)操作簡(jiǎn)單、易于維護(hù)、經(jīng)濟(jì)性高、可靠性高的釋放器，安裝在深海測(cè)試平臺(tái)上，由遠(yuǎn)程控制或ROV的機(jī)械手操作，完成釋放安裝在釋放器上的儀器設(shè)備的任務(wù)。 4）通過(guò)有限元分析軟件對(duì)重要的機(jī)構(gòu)部件進(jìn)行靜力分析和屈曲分析，根據(jù)分析結(jié)果剔除危險(xiǎn)截面、危險(xiǎn)點(diǎn)，控制最大形變量，提高深海測(cè)試平臺(tái)整體的安全系數(shù)，保證深海測(cè)試平臺(tái)在深海高壓、低溫環(huán)境下長(zhǎng)時(shí)正常工作。
[Abstract]:Deep-sea test platforms are placed on the deep sea floor to monitor the deep-sea marine dynamic environment, chemical environment, geophysical environment for a long time in real time, and the monitoring data are passed through the main connection box. A test system for transmission of secondary connection boxes and optical cables to coastal base stations in real time. The idea of a deep-sea test platform was originally developed by the Cold War U.S. military to monitor underwater acoustic surveillance, mainly from ships from other countries. Deep-sea test platforms are now more widely used and functional, providing more reliable real-time data for the study of deep-sea ecosystems, supporting research on the effects of the oceans on climate, and monitoring the oceans in real time. Provide early warning for tsunami and other disasters caused by undersea earthquake. Human exploration of the deep seabed is still in its infancy, and the design of the deep-sea test platform is also in the initial stage of exploration. The implementation of this project has played a certain role in promoting the development of marine exploration in China. In cooperation with the second Oceanographic Research Institute of the State Oceanic Administration, the purpose of this project is to design a deep-sea testing platform that can meet the requirements of use. After analyzing and optimizing the stability of the whole platform when it is free sinking and equipment releasing, the main work is as follows: 1) according to the requirements of the project group, the design size is appropriate, the structure is reasonable, convenient for long-distance transportation, and can carry two seismographs. A magnetometer, a control bin, a battery bin, and a deep-sea test platform for associated cables and spare parts. 2) A three-dimensional data model of the deep-sea test platform and its associated institutions, using fluid analysis software, The stress and stability of the whole platform in the process of free descent in water are analyzed. According to the results of the analysis, the shape design, the installation position of the instrument, etc. 3) the release device with simple operation, easy maintenance, high economy and high reliability is designed. Installed on a deep-sea test platform, operated by a remote control or ROV manipulator, the task of releasing instruments and equipment mounted on the release device is completed. 4) static analysis and buckling analysis of important mechanism components are carried out by means of finite element analysis software. According to the analysis results, the dangerous section and dangerous point are eliminated, the maximum shape variable is controlled, the safety coefficient of the whole deep-sea test platform is improved, and the deep-sea test platform works normally for a long time under the environment of deep-sea high pressure and low temperature.
