基于 AQWA的滑翔圆碟的水面漂移特性研究

摘要

Use the marine engineering water dynamic analysis software AQWA to study the drift performance of the disk type underwater glider. Under the condition of regular wave, the wave load, the additional mass factor, the response amplitude operators (RAOs) and the drift trajectory of the glider are predicted. The wave load data are fitted in Matlab and Origin, and the expressions of the wave loads are obtained in the normal range and different wave direction. The results show that the RAOs value and the drift trajectory of the glide are reasonable, and it have a stable performance. It provide a new idea for the research of working performance of the glider.%利用海洋工程水动力分析软件AQWA对一种新型无尾翼滑翔圆碟的水面漂移特性进行研究。在规则波浪条件下，对滑翔圆碟的波浪载荷、附加质量系数、运动响应幅值算子（RAOs）及水面漂移轨迹进行预报。最后，利用Matlab对波浪载荷数据进行拟合，得到在常见波频范围内、不同浪向角作用下，滑翔圆碟波浪载荷的表达式。研究结果表明，在常见波频范围内，滑翔圆碟的RAOs值及水面漂移轨迹较为合理，拥有较稳定的工作性能；拟合得到的波浪载荷表达式拥有较高精度，基本满足实际的工程计算需求，为滑翔圆碟水面漂移特性的研究工作提供一种新思路。
