The invention provides an electromagnetic damping device for an unmanned underwater glider and the unmanned underwater glider, and relates to the technical field of underwater gliders, the electromagnetic damping device for the unmanned underwater glider comprises an alternating current power supply, a plurality of electrode plates and a plurality of magnets; the electrode plates and the magnets are sequentially arranged on the wing face in a crossed mode, the magnetic poles of every two adjacent magnets are arranged oppositely, the alternating current power source comprises a live wire and a null line, and any two adjacent electrode plates are connected with the live wire and the null line respectively. Compared with the prior art, the momentum is periodically input to the boundary layer through the periodic electromagnetic force, and vibration reduction is performed by adopting a new principle of changing the falling frequency of the trailing vortex and avoiding structural resonance. Compared with a constant electromagnetic force control technology, the method does not need to completely restrain falling of the trailing vortex, only needs to change the falling frequency of the trailing vortex, needs less momentum provided for a boundary layer, can achieve the purpose of vibration reduction under small electromagnetic force, and is more energy-saving.
本发明提供一种用于无人水下滑翔机的电磁减振装置及无人水下滑翔机,涉及水下滑翔机技术领域,用于无人水下滑翔机的电磁减振装置包括:交流电源、多个电极板和多个磁体;电极板和磁体依次交叉布设于翼面上,相邻的两个磁体的磁极排列相反,交流电源包括火线和零线,任意相邻的两个电极板分别与火线和零线相接。相比于现有技术,本发明通过周期性电磁力向边界层周期性输入动量,采用改变尾涡脱落频率,避免结构共振的新原理来减振。相比于常电磁力控制控制技术,本发明无需将尾涡脱落完全抑制,而仅仅只需改变其脱落频率,向边界层提供的动量需求较少,在较小的电磁力下即可达到减振目的,更为节能。
