摘要

波浪滑翔器是一种广泛应用于海洋探测的新型海洋移动观测平台,往往将传感器搭载于波浪滑翔器船体上。为确保搭载不同传感器的波浪滑翔器安全进行海洋探测任务,通过船舶稳性原理初步确定波浪滑翔器船体的搭载范围,通过AQWA对不同搭载配置的波浪滑翔器船体进行规则波与不规则波仿真,探究波浪条件对船体横摇运动的影响并确定了3级海况下波浪滑翔器的搭载范围,结果表明:当有效载荷重量超过船体质量的4%(2 kg)或桅杆高度超过1 m时,初稳性高值GM会显著减小;在3级海况下,当搭载载荷质量与搭载高度乘积MH < 2 kg·m时能够确保波浪滑翔器进行海洋探测任务时能够安全运行;通过水池实验与海试实验对仿真结果进行了可靠性验证。为波浪滑翔器海洋探测的搭载设计提供了有效参考。

Abstract

The wave glider is a new type of mobile ocean observation platform widely used in marine exploration, often with sensors mounted on the float. In order to ensure the safe operation of the wave glider carrying different sensors for marine exploration tasks, the range of payload for the wave glider float was initially determined based on the principle of ship stability. AQWA was used to simulate regular and irregular waves for wave glider float with different payload configurations, exploring the influence of different wave conditions on the roll motion of the float. The range of payload for the wave glider under sea state 3 was determined. The results show that when the payload weight exceeds 4% (2 kg) of the float mass or the mast height exceeds 1 meter, the GM value will significantly decrease. Under sea state 3, when MH is less than 2 kg·m, the wave glider can safely operate for marine exploration tasks. The simulation results are validated through pool experiment and sea trials experiment, providing effective reference for the design of wave glider's payload for marine exploration.
