Testing device and method for upward floating icebreaking of submarine model in ocean current environment

The invention discloses a test device and method for upward floating icebreaking of a submarine model in an ocean current environment. The test device comprises a current making system, an icebreaking simulation system, a shooting system and a sensing system. The flow making system comprises a pool body and an internal circulation flow making machine. The icebreaking simulation system comprises a submarine model, a base and a plurality of jacking devices. And the plurality of jacking devices are in spherical hinge connection with different positions of the submarine model so as to adjust the height and the pitching angle of the submarine model. The shooting system comprises an underwater shooting device and an overwater shooting device. The sensing system comprises a pressure distribution sensor, a pressure sensor and an acquisition instrument. The pressure distribution sensor is installed on the submarine model, and the pressure sensor is installed in the pool body and supports the base. The acquisition inst
