摘要: 计算机仿真或水槽实验的方法难以准确反映真实海况下的波高和波周期与波浪滑翔器的波浪驱动速度的映射关系。文中采用“黑珍珠”小型波浪滑翔器搭载声学多普勒流速剖面仪(ADCP)、波浪传感器和全球定位系统等载荷, 获得了波高、波周期、流速以及位置坐标等数据, 利用ADCP底跟踪模式测量的波浪滑翔器对地速度矢量减去ADCP测得的剖面流速矢量, 计算出波浪滑翔器的波浪驱动速度矢量, 建立波浪驱动速度与海浪波高和波周期的散点图, 并采用拟合曲线找出波浪驱动速度与海浪参数之间的映射关系。文中推导出的波浪驱动速度在一定参数范围内与波高呈正相关、与波周期呈负相关的预测模型, 可为波浪滑翔器的波浪动力转换机构优化设计提供指导。Abstract: It is difficult to accurately reflect the mapping relationship among the wave height, wave period under real sea con-ditions, and wave-driven velocity of a wave glider via computer simulation or water tank experiments. In this study, wave height, wave period, velocity, and position coordinate data were obtained using an acoustic Doppler current profiler(ADCP), wave sensor, and global positioning system(GPS), which were installed on a Black Pearl wave glider. The wave-driven velocity vector of the wave glider is calculated by subtracting the profile velocity vector from the ground velocity vector. The profile velocity vector is directly measured using the ADCP, whereas the ground velocity is measured using the ADCP bottom tracking mode and GPS data. Finally, scatter plots of wave-driven velocity, wave height, and wave period are constructed, and the mapping relationship between wave-driven velocity and wave parameters is determined by fitting curves. The deduced wave-driven velocity in this study is positively correlated with the wave height and negatively correlated with the wave period within a certain range of parameters. The relationship serves as an important basis for the optimal design of the wave dynamic transfer mechanism of a wave glider.
