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 ...
