【摘要】 表层漂流浮标在应用于海洋调查研究时,浮标体外形对浮标通讯稳定性及数据回收等会产生一系列影响,也直接制约浮标使用寿命。为此,考虑减少风阻和水阻,减小浮标体对水帆运动的影响,提出了一种新型的适用于近远海海洋观测的表层漂流浮标体葫芦形外形设计方案。结合流体力学理论分析,运用Solid Works软件分别对葫芦形浮标体和常用的圆柱形浮标体建模,并利用Workbench软件CFX流体分析模块开展了流体分析和比较,结果表明葫芦形浮标体所受压力更均匀,其水下部分压力值较圆柱浮标体减小约28%,证明葫芦形外形浮标体更具可靠性。更多还原

【Abstract】 In the application of surface drifting buoy in marine research,the buoy body shape has a series of effects on buoy communication stability and data recovery,directly restricting the buoy life. To reduce the wind resistance and water resistance,and the influence of the buoy on the movement of the drogue,this paper presents a new design scheme of the gourd shape of the surface drifting buoy suitable for near-ocean and ocean observation. Based on the theory of hydrodynamics,the Solid Works software is used to model the gourd buoy and the commonly used cylindrical buoy,and the CFX fluid analysis module in the Workbench software is used to carry out the comparison and analysis of fluid. The results show that the pressure of the gourd buoy is more uniform,and the pressure value of the underwater part is about 28% lower than that of the cylindrical buoy,indicating that the gourd shape design is more reliable.更多还原
