中文摘要:
      海洋观测浮标系统应用广泛,浮标体的平衡性能是影响海洋观测浮标使用的重要因素之一(着重观测波浪等水文参数除外)。本文以一种主体直径为2.3m的浮标体为例,运用动力学平衡理论, 通过数学分析法进行推演计算,分析后得到了此浮标体的重心和浮心的位置。其中,重心位于主浮体的中轴线偏下位置;按照浮标体倾斜一定角度的情况下,推算出浮标体浮心位置,并由此得出其稳心的位置。依据计算,得出浮标体倾斜20°的情况下,此浮标体依然处于稳态平衡,理论结果表明此浮标体设计具有一定的可行性。通过海上实际测试,验证了理论计算分析的正确性。本文对浮标体平衡性的研究采用了理论分析与实验印证相结合的方法,其分析计算方法具有普适性,适用于其他型号的海洋观测浮标体,乃至所有水面浮体的平衡性分析,可为水面浮体设计提供借鉴。
英文摘要:
      Ocean observation buoys are widely used. The balance of the ocean buoy body is one of the important factors affecting the performance of the buoy system (Except for measuring the hydrological parameters such as wave). Taking a small buoy with a main body diameter of 2.3 m as an example, this paper deduces and calculates the position of the center of gravity and buoyancy of the buoy by using the theory of mechanical balance and mathematical analysis method. The center of gravity is located on the central axis of the main buoy and is downward from the center of the buoy. When the buoy tilts certain degrees, the buoy's center of gravity is calculated. The coordinates and the stable position of the center are obtained. It is also calculated that the buoy is still in steady state equilibrium when its inclination is 20 degrees. The theoretical results show that the design is feasible. The correctness of theoretical calculation and analysis is verified by actual test at sea, and the buoy is still in stable equilibrium state when its inclination is serious. In this paper, theoretical analysis and experimental verification are used to study the balance of buoys.The analysis and calculation method in this paper is universal and suitable for the balance analysis of other types of buoys, even all surface buoys, and it is expected to provide reference for the design of floating body on water surface.
