This paper uses pectoral fins fluctuation pattern class triangular skate as the object of study. The skate generates waveforms through its broad pectoral fins, which are transmitted backwards to push the water backwards, and the reaction force of the water obtained is the forward thrust i.e. the MPF pattern. The fins are designed to meet the fluctuation pattern of the sinusoidal function. A prototype pectoral fin of the ray is analysed to establish the kinematic model of the fluttering wing, the envelope coefficients are designed to decouple and simplify the kinematic equations, and a three-dimensional mesh is drawn using MATLAB; fluid simulation is carried out by Fluent to obtain the vortex cloud; the bionic ray is tested and tested to meet the actual requirements.
