Abstract

The invention provides a bionic pectoral fin motion device designing method. According to design requirements of a bionic pectoral fin motion device, swinging and twisting motions of a bionic pectoralfin are finished by designing a main motor, a sub motor, a main beam, a crankshaft and a fixing bracket and an assembling method; and by using the technical scheme of the bionic pectoral fin motion device designing method, the technical problem that both swinging angle and twisting angle accurate control and simple mechanism of the bionic pectoral fin in a device obtained by an existing designingmethod cannot be realized is solved.

Description

technical field [0001] The invention relates to the technical field of underwater bionic technology, in particular to a bionic pectoral fin movement device. Background technique [0002] Bionic pectoral fin propulsion is a propulsion method that imitates the movement pattern of the pectoral fins of the marine organism manta ray. It has the advantages of high propulsion efficiency, low-speed maneuverability, and small water disturbance. An important development direction of advancing technology. The analysis of the movement characteristics of the pectoral fins of the manta ray found that the movement of the pectoral fins is a coupled movement of two degrees of freedom, that is, when the pectoral fins move, there are up and down flaps and fluctuations along the body length at the same time, and the amplitude of the fluctuations ranges from the tip of the pectoral fin to the Wing roots gradually decrease. Aiming at the motion device design of this bionic motion mode, colleges...
