Resistance performance optimization method and device based on double-tail-fin ship and storage medium

The invention is suitable for the field of ships, and provides a double-tail-fin ship-based resistance performance optimization method, which comprises the following steps that: a server obtains a simulation model of an actual target double-tail-fin ship based on tail fin characteristic parameters for describing the actual target double-tail-fin ship; performing fluid mechanics calculation based on the simulation model to obtain a resistance coefficient of the simulation model; dynamic characteristic parameters of the tail fins are dynamically adjusted, and when the resistance coefficient corresponding to the dynamic characteristic parameters of the tail fins is minimum, the dynamic characteristic parameters of the tail fins are used for constructing a simulation model of the double-tail-fin ship. According to the method, the parameterized design thought is applied to the tail fin curved surface design of the twin-tail-fin ship, the shape of the tail fin curved surface of the twin-tail-fin ship is controlled
