The invention discloses a fuselage crossing point simulating device for an airplane main landing gear ground test, and relates to the technical field of design of airplane structure testing devices. The fuselage crossing point simulating device is used for simulating airplane main landing gear fuselage crossing points; bolt holes I are formed in the edge of a base; a supporting surface is arranged in the middle of the base; a first fixing supporting seat and a second fixing supporting seat are arranged on the supporting surface; bolt holes II are formed between the first fixing supporting seat and the second fixing supporting seat on the supporting surface; a fixing seat adopts a groove structure; bolt fixing holes are formed in the corresponding positions of the groove edges; a second stepped hole (22) is formed in one end of the fixing seat, and is coaxial to a first stepped hole in the base; the base and the fixing seat are mounted in a coordinated manner to fix an airplane main landing gear. The provided fuselage crossing point simulating device avoids complex loading, and is simple in structure, convenient to manufacture, strong in carrying capacity, long in service life, convenient to assemble and disassemble, high in mounting accuracy, high in device stability, safe and reliable.
Description
technical field [0001] The invention relates to the technical field of aircraft structure design, in particular to a fuselage intersection simulation device for aircraft main landing gear ground tests. Background technique [0002] The fuselage intersection of the aircraft's main landing gear is the main supporting structure of the main landing gear, which needs to be replaced by dummy parts in the strength test. In the design of the fake part, due to the limitations of materials used and processing costs, it is not possible to use a design that is exactly the same as the aircraft structure. The commonly used dummy structure is to design the A-point support and the B-point support independently, and fix them on the same platform with the test piece during installation. Due to the separate design and processing, the bearing capacity is weak, and it is difficult to ensure the correct installation position of the test piece during installation, and this structure has problems ...
