The invention provides a system and the method for testing the structural strength of the ship bottom of a seaplane. The system comprises a test piece, a restraining device and a first loading device,wherein the test piece comprises a ship bottom wall plate 1, a ship bottom frame 2, a side wall frame 3 and a side wall plate 4, a constraint frame and a constraint clamp for limiting movement of thetest piece are arranged at the first end of the test piece in the heading direction, and constraint devices for limiting left-right movement and up-down movement of the test piece are arranged on thetwo sides of a ship body of the test piece; a loading clamp and a first loading device are arranged at the second end of the test piece in the heading direction, and the pressurizing end of the firstloading device makes contact with the loading clamp through a loading cushion block to load the test piece; and the shape of the cushion block is consistent with that of the end face of the loading clamp. According to the system and method for testing the structural strength of the ship bottom of the seaplane, the test piece required for verifying the structural strength of the ship bottom can beproduced at low cost; and the loading scheme is simple.
Description
technical field [0001] The invention belongs to the technical field of aircraft strength testing, and in particular relates to a system and method for testing the strength of the bottom structure of a seaplane. Background technique [0002] The bottom structure is one of the main load-bearing structures of seaplane / amphibious aircraft. It not only bears the bending moment of the fuselage, but also bears the distributed pressure or local pressure, which plays a very important role in the safety of the aircraft. Therefore, it is necessary to pass test verification methods to ensure that the ship bottom structure meets the static strength requirements. [0003] For the strength test method of the ship bottom structure, the conventional method is to produce a full-scale model of the aircraft structure with a partial frame section, and apply tangential shear force and distributed pressure load for the test. [0004] The production cost of the conventional test method model is hi...
