【摘要】：深海测试平台是在布放在深海海底，对深海海洋动力环境、化学环境、地球物理环境进行长时间实时监测，并将监测数据通过主接驳盒、次接驳盒和光缆实时传输至海岸基站的测试系统。深海测试平台的想法最初产生于冷战时期的美国军方，其目的是海底水声监视，主要是监视其他国家的舰艇。如今深海测试平台的用途和功能更为宽泛，可以为深海生态系统的研究提供更多更可靠的实时数据，，为海洋对气候的影响的研究给予支持，可以实时进行海洋监测，为海底地震引起的海啸等灾害提供预警等。人类对深海海底的探测尚处于起步阶段，深海测试平台的设计也处于初步探索阶段，本课题的实施对我国海洋探测的发展起到一定的推动作用。本课题与国家海洋局第二海洋研究所合作，目的在于设计能够满足使用要求的深海测试平台机构，并分析优化整个平台自由下沉和设备释放时的稳定性，主要完成如下设计工作： 1）按照项目组要求，设计尺寸大小合适，结构外形合理，便于长途运输，能搭载两个地震仪、一个磁力仪、一个控制仓、一个电池仓，以及相关电缆与零配件和的深海测试平台。 2）建立深海测试平台及其相关机构的三维数据模型，使用流体分析软件，分析整个平台在水中自由下降过程中的受力情况和稳定性，并根据分析结果优化外形设计、仪器的安装位置等。 3）设计操作简单、易于维护、经济性高、可靠性高的释放器，安装在深海测试平台上，由远程控制或ROV的机械手操作，完成释放安装在释放器上的仪器设备的任务。 4）通过有限元分析软件对重要的机构部件进行静力分析和屈曲分析，根据分析结果剔除危险截面、危险点，控制最大形变量，提高深海测试平台整体的安全系数，保证深海测试平台在深海高压、低温环境下长时正常工作。
[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.
