A magnetic force driven fluctuation propelling type bionic fish comprises an electromagnetic trunk, the electromagnetic trunk comprises at least two magnetic bearing pieces and a plurality of trunk units, the magnetic bearing pieces and the trunk units are sequentially connected at intervals from front to back, and the adjacent magnetic bearing pieces are oppositely arranged; the two ends of the trunk unit are connected to the middles of the two adjacent magnetic bearing pieces correspondingly, so that the two adjacent magnetic bearing pieces can rotate relatively, and electromagnets are arranged on the left portion and the right portion of the side, facing the adjacent magnetic bearing piece, of any magnetic bearing piece correspondingly. According to the scheme, the electromagnets are arranged on the left portions and the right portions of the magnetic bearing pieces respectively, the polarities of the electromagnets are changed by controlling the directions of the electrifying currents of the electromagnets, the left portions/the right portions of every two adjacent magnetic bearing pieces can be close to each other or away from each other, and therefore the bionic fish can form a fluctuating propelling mode. Compared with the prior art, the scheme has the advantages of being good in bionic effect, accurate in action, large in bending amplitude, flexible in swinging, large in propulsive force, low in noise and the like.

    一种磁力驱动的波动推进式仿生鱼,包括电磁躯干,电磁躯干包括至少两个承磁片和若干躯干单元,承磁片和躯干单元沿从前向后依次间隔连接,相邻的承磁片相对设置,躯干单元的两端分别连接于相邻两个承磁片的中部并使得相邻两个承磁片可相对转动,任一承磁片的朝向相邻承磁片的一侧的左部和右部分别设有电磁铁。上述方案中由于在承磁片的左部和右部分别设置有电磁铁,通过控制电磁铁的通电电流方向以改变电磁铁的极性,即可使得相邻两个承磁片的左部/右部相互靠近或远离,从而能够使得仿生鱼形成波动式的推进模式。与现有技术相比,上述方案具有仿生效果好、动作准确、弯曲幅度大、摆动灵活、推进力大、噪音小等优点。
