海洋物性监测小型浮标稳性设计

Stability Design of Small Buoy for Marine Physical Property Monitoring

根据海洋资料浮标原理设计了直径为3 m的圆盘式小型浮标,拟将其用于搭载国产气象水文传感器进行深远海应用示范。为了验证该浮标设计能够满足项目应用需求,文中统计了浮标工作海域的环境参数和浮标的质量、重心、浮心、吃水和排水等设计参数,参照船舶静力学原理及波浪理论,通过计算浮标的初稳性和大倾角稳性完成浮标的稳性计算,得到了浮标的初稳心高度、稳心半径、固有周期、自由最大横摇角、静稳性曲线、动稳性曲线、最大复原力臂、极限静横倾角、稳性消失角和稳性衡准数等稳性参数。分析这些参数,结果表明:该浮标设计完全满足《国内航行海船法定检验技术规则(2011)》对海洋浮体稳性的要求,这说明该浮标设计参数合理、方案可行,可应用于项目的浮标研制工作。

A small disc buoy with a diameter of 3 m is designed based on the principle of ocean data buoy and is to be used to carry the domestic marine meteorological and hydrological sensors for far-reaching marine application demonstration.In order to verify that the design of the buoy can meet the project application requirements,the environmental parameters of the buoy working area and the design parameters of the buoy,such as its mass,gravity center,buoyancy center,draft and drainage,are analyzed,and the stability calculations are completed by referring to the ship static principle and wave theory and calculating the initial stability and large dip stability of the buoy.The stability parameters of the buoy are thus obtained,which include initial stability center height,stability center radius,inherent period,free maximum roll angle,static stability curve,dynamic stability curve,maximum restoring force arm,ultimate static tilt angle,stability vanishing angle and stability criterion.By analyzing all the parameters,it is shown that the design of the buoy fully meets the requirements of the“Technical Rules for Statutory Inspection of Domestic Navigating Vessels(2011)”for the stability of ocean buoys,indicating that the design of the buoy is reasonable in parameters and feasible in scheme,and can be applied to the buoy development of the project.
