Marine pump operation environment simulation system and method

The invention provides a marine pump operation environment simulation system and method, and belongs to the field of fluid machinery numerical calculation. The system mainly comprises a model acquisition module, a motion law acquisition module and a model setting module. The motion law acquisition module acquires a marine pump swing law and a fluid medium impeller rotating shaft position change law according to the three-dimensional model established by the model acquisition module; the model setting module imports grid data obtained after the motion law and the three-dimensional model are subjected to grid division into a fluid analysis unit for processing, and simulates and builds a complete marine pump operation environment. The periodic angular displacement motion law of swinging of the marine pump is loaded into the fluid medium in a function form, so that the fluid medium and the marine pump are kept consistent in motion, and the design reasonability and the operation stability of the marine pump are im
