| 摘 要： | 为验证研制的国产气象水文传感器的性能,设计了直径3 m的圆盘式小型浮标,拟搭载所有传感器在2000 m以深海域开展应用试验。统计了试验海域的有义波高、波浪周期、最大风速和表层流速等环境参数,计算了浮标的质量、重心、吃水、受力投影面积和惯性矩等设计参数。以三维势流理论和波浪辐射-绕射理论为基础,使用AQWA软件在频域内对浮标进行水动力计算,仿真了浮标工作时所受的一阶波浪力、附加质量、附加阻尼和运动幅值响应因子,通过仿真结果对浮标设计方案进行优化,优化后的浮标计算结果随波浪频率变化平缓,幅值合理且无激增点,表明该浮标与工作海域内的波浪没有发生明显谐振,对环境载荷有足够的承受能力,方案可用于浮标研制。

| Abstract: | A 3 m diameter disc buoy was designed in order to verify the performance of the domestic meteorological and hydrological sensors. It is planned to carry out the application test of all the sensors in the sea area with a depth of more than 2 000 m. The environmental statistics of the sea area where the buoy will be deployed, such as wave height, wave period, maximum wind speed and surface velocity, are proposed. The design parameters of the buoy, such as mass, center of gravity, draft, projection area of the external force and moment of inertia, are calculated. The hydrodynamic calculation of the buoy is carried out in the frequency domain by using AQWA software based on the three dimensional potential flow theory and wave radiation-diffraction theory, the first-order wave force, additional mass, additional damping and response amplitude operators of the buoy are simulated. The buoy design scheme is optimized by the simulation results. The calculation results of the optimized buoy change smoothly with the wave frequency, The amplitude is reasonable and there is no singularity in it, the results indicate that there is no obvious resonance between the buoy and the waves in the working sea area, and the buoy has enough bearing capacity for the environmental load. The scheme can be used in the development of buoy. |
