摘要

摘要: 波浪滑翔器纵向运动速度受海况影响而发生变化, 揭示波浪滑翔器纵向运动速度与浪高以及波周期之间的关系对提升和改进波浪滑翔器的动力性能具有重要意义。以“海哨兵”波浪滑翔器为研究对象,首先建立波浪滑翔器动力学模型; 然后仿真获取其纵向速度与波高及波周期的定量关系; 最后试验获取波浪滑翔器在真实海况下的纵向速度, 并与仿真得到的理论值进行对比分析。研究结果表明, 波周期一定时, 波浪滑翔器纵向速度与波高的平方根成正比; 波高一定时, 波浪滑翔器的纵向速度与波周期的倒数成正比。通过动力学方程推导和试验数据分析, 建立了波浪滑翔器纵向速度与海浪参数的定量关系, 为波浪滑翔器结构参数优化和后续设计提供了依据。

Abstract: The longitudinal velocity of a wave glider is influenced by the sea states. It is necessary to explore the relations of the longitudinal velocity of the wave glider with wave height and wave period for improving the dynamic performance of the wave glider. In this study, a dynamic model of the Sea Sentry wave glider was established to obtain the quantitative relation of its longitudinal velocity with the wave height or the wave period, and the simulation results of the longitudinal velocity were compared with the data obtained in sea trials. It is shown that the longitudinal velocity of the wave glider is proportional to the square root of the wave height when the wave period is constant, and is proportional to the reciprocal of the wave period at a certain wave height. In addition, the validity of the proposed dynamic model was verified. This study may provide the basis for structural parameter optimization and subsequent design of the wave gliders.
