    摘要:

    本文针对海流激励下Argo浮标的运动响应特性问题,建立了浮标运动与海流数学模型,对Argo浮标及加入十字形帆后纵平面的运动响应特性进行了仿真计算,分析了不同尺寸的帆对响应速度的影响,对帆的尺寸提出了设计建议。结果表明:随着帆长度的增加,其横向响应速度呈现先变快后变慢的趋势,帆的尺寸不同对其影响程度也不同,各宽度的帆均存在最佳的长度配对方案。在海流作用下,加入十字形帆可以有效提高Argo浮标的响应速度,在5s响应时间处,响应速度相比不加帆的浮标可增大30.4%,俯仰角及俯仰角速度变化范围均有一定的减小。

    Abstract:

    The motion response characteristics of Argo buoy under ocean current excitation was dealt with in this paper, the mathematical model of motion was established. The motion response characteristics of longitudinal plane of Argo buoy and the buoy that adding one cross-shaped sail were simulated, the influence of different size of sails on response speed was analyzed, the design suggestions of the size of sail were proposed. The motion response of Argo buoy was affected by adding the cross-shaped sail as the length of the sail increases, the lateral response speed tended to become faster first and then slower, the influence level varied with the size of sail. There was an optimal combination of sails of all widths. Under the action of the current, the addition of a cross-shaped sail effectively improved the response speed of the Argo buoy. At the response time of 5s, the response speed was increased by 30.4% compared with the buoy without sail, and the range of pitch angle and pitch angular velocity was reduced.
