摘要	海洋监测是人类认识海洋、研究海洋的有利工具，海洋自动观测仪器又是海洋监测技术最基本的硬件单元。文章介绍了一种具有自主知识产权的海洋仪器产品——节能型自治式多功能海洋环境监测系统，并对其做了静力分析和姿态计算。该测量系统将定点锚泊潜标和浮标技术相结合，并创新性的融进了节能技术，使其具有长期、安全和多参数测量的工作特点。为确保系统能在水下长期可靠地工作，文章对系统在水下的受力状况和姿态进行了计算。由于系统潜标式主浮体在水下几十米，海面波浪对其影响较小，仅对系统在海流的作用下进行水下静力分析。计算中首先根据总体技术要求进行合理的简化和假设，建立水下系统的数学模型，编制系统在水下的受力和姿态计算软件，完成系统的结构配置、受力分析和水下姿态的计算。值得注意的是，该系统的潜标式主浮体受力分析方法与传统简单构形（一个浮体，一根索和一个锚）的分析方法不同，因为该潜标式主浮体不但受到下端缆绳的拉力，而且还受到连结上端搭载平台缆绳的拉力，同时还要考虑进变化海流对缆绳的作用。最后，用MATLAB编制了相应程序。该程序操作方便，每次任务确定之后，只需向计算机输入阻尼系数、浮力重力值、浮球直径及潜标长度等参数，程序将自动计算出水下系统在流速范围内各部件的横倾角、缆绳拉力及拉力与水平线（垂直线）夹角等有关参数，供系统配置做参考。
其他摘要	Ocean Observation is neccesery for people to learn and study ocean. The various marine monitoring instuments play an basic role in marine monitoring. A new environmental monitoring system under the water is introduced in the paper, which is more effective with multi-functions. The static analysis and attitude calculation of the system are given here also. This monitoring system combines buoy with main submersible buoy to compose a new type of energy-saving system. So it has the operating features such as long-term reliability, safe and multi-parameter. For maintaining system’s long-term reliability, the underwater static analysis and attitude calculation of the system is often a necessary. Cause top float is under water tens of meters and surface waves have relatively less influence on it, we only need to make the static analysis. Before calculating, we should first do some reasonable simplification and assumption, then build the mathmatical model and make system’s force and attitude calculation programes to finish the system’s configuration, stress analysis and attitude under water. It is noteworthy that the analysis of the main submersible buoy in this system is quite different from the traditional simple configuration’s(only one buoy, one cable and one mooring system). In this system, the main submersible buoy not only given the forces by the cable below, but also loaded the forces from the top buoy. Besides those, the force that various flow load on the cable should be considerd in also. Finally, an easy operational calculation programe using MATLAB is made. In this programe, inputing parameters such as damping coefficient, buoyancy, gravity, buoy’s diameter, submersible buoy’s length, and so on, the stress and obliquity of buoy, main submersible buoy and cable at the flow velocity between and can be calculated automatically. It provides a reference for system’s configuration.
