摘要
运动性能是浮标设计中的关键问题之一。文中对直径10 m的圆盘型海洋资料浮标的运动性能进行了数值模拟和试验研究。建立了浮标的有限元模型,采用势流理论进行计算分析,获得了浮标运动响应的传递函数。通过对数值计算结果与模型试验结果进行比较,验证了数值计算方法的有效性。在此基础上,结合我国南海海区海况资料,应用谱分析法对其在极限海况下的运动响应进行了短期预报。该研究结果对浮标前期设计具有参考意义。
Motion performance is one of the crucial points in the data buoy design. Numerical simulation and model test have been conducted on the motion performance of the large disc-type ocean data buoy with a diameter of 10 m. The finite element model of the data buoy is built and hydrodynamic analysis is performed by applying the Potential Flow Theory, obtaining the transfer function of buoy motion response. Numerical computed results are compared with experimental results and the accuracy of numerical model has been verified. On the basis of calculations and sea data of the South China Sea, the spectrum analysis method is applied to predict short-term motion response of the buoy under extreme sea states. The results of the study can serve as a reference for the preliminary design of the buoy.
