Problems solved by technology

For the type selection and test verification of the butt joint structure of the lower wall plate in the wing root connection area, the common method is to simulate and replace the actual butt joint configuration with a straight butt joint structure, but the influence of the dihedral angle at the wing root of the civil aircraft structure is not considered. Sufficient, the verification of the actual force transmission path is not accurate enough

Abstract

The invention discloses a butt joint test device and test method for a wing root lower wall plate of an aircraft wing with a dihedral angle, and relates to the technical field of aircraft lower wall plate butt joint test, and the device comprises: a test piece which comprises an outer wing side wall plate and a central wing side wall plate which are transversely arranged, wherein the outer wing side wall plate and the central wing side wall plate are fixedly connected through a connector; a fixing unit which is connected with the central wing side wall plate and is used for fixing the test piece; a support unit which is connected with the connector and is used for providing support for the test piece; and a lever unit which is connected with the outer wing side wall plate and is used for transmitting and amplifying an external load. According to the invention, the actual force transmission path of the lower wall plate of the wing root connection area can be simulated more accurately, and the analysis method of the wing root connection area can be verified more fully.

Description

technical field [0001] The invention relates to the technical field of butt joint test of the lower wall plate of an aircraft, in particular to a test device and a test method for the butt joint test of the lower wall plate of the wing root of an aircraft wing with dihedral. Background technique [0002] For the structure of modern civil aircraft, the connection relationship of the wing root connection area where the central wing box and the outer wing box are docked is complicated, and the shear force and bending moment load are high. The butt joint structure of the lower wall plate affects the overall scheme of the wing root connection area. Under the action of flight load, it is subjected to tensile load, and tests need to be carried out to verify its structural bearing capacity, assembly characteristics and related analysis methods. For the type selection and test verification of the butt joint structure of the lower wall plate in the wing root connection area, the commo...
