| 摘 要： | 氮气浮标是一种新型的剖面浮标,通过增加蓄能器作为被动浮力调节模块,可以利用海洋压差实现更有效率的剖面运动。由于蓄能器的加入,氮气浮标的运动特性相对于常规浮标有所变化。基于一款深海剖面浮标,利用理论分析和运动仿真的方法研究了氮气浮标的运动特性,对氮气浮标主动体积改变量与剖面运动深度之间的对应关系、氮气浮标的剖面运动形式以及氮气浮标的定深悬浮稳定性进行研究。研究表明,氮气浮标只需要主动对浮标体积做较小的改变即可完成同等深度的剖面运动,节省了浮标完成一次剖面运动的能量消耗。但蓄能器的引入增加了浮标完成剖面运动需要的时间,且给浮标的运动带来了突变性和不稳定性。

| Abstract: | Nitrogen profiling float can utilize oceanic pressure to achieve a more efficient profiling movement by adding energy accumulator as passive buoyancy adjustment module. Due to the addition of the accumulator, the motion charateristics of nitrogen floats are different from those of conventional ones. In this paper, the movement characteristics of nitrogen floats are studied by means of theoretical analysis and motion simulation based on one type of deep-sea profiling float. The researches include the corresponding relationship between the active volume change and the depth of profiling movement, the qualitative problem of profiling movement and the stability problem of depth-keeping. The results show that the nitrogen float can complete the same depth profiling movement only by making minor changes in the volume, which saves the energy consumption to complete a profiling movement. However, the accumulator increases the time needed for the float to complete the profiling movement, and brings sudden change and instability to the movement of the float. |
