The invention relates to the technical field of aircraft structure strength test loading, in particular to a double-layer floor beam loading device for aircraft structure strength test. Aircraft structural strength test double-layer floor beam loading device, including: loader; loading beam; main loading rod assembly, acting on the loading beam; two joint levers, the bottoms of the two ends of the loading beam are respectively connected to the single ear and the joint lever at the corresponding end Connection; two cabin floor beam loading components, connected with the combined lever and the cabin floor; two force transmission components, connected with the combined lever; two cargo compartment floor beam loading components, connected with the force transmission component and the cargo compartment floor. The double-layer floor beam loading device for aircraft structure strength test of the present invention can simultaneously load the passenger cabin floor beam and the cargo cabin floor beam, thereby adapting to the loading requirements of the double-layer cabin floor beam of a new large passenger aircraft, and can fully verify the cabin floor beam and related structures The strength makes the test results more accurate and efficient.
Description
technical field [0001] The invention relates to the technical field of aircraft structure strength test loading, in particular to a double-layer floor beam loading device for aircraft structure strength test. Background technique [0002] In the current static / fatigue test of the full-scale aircraft structure, it is necessary to simulate the passenger and cargo loads in the cabin and the aerodynamic inertial loads of the fuselage for loading. In the previous tests, this part of the load was usually transferred to the outside of the cabin, and the load was carried out by pasting adhesive tape on the skin of the fuselage. Although this simplified treatment will not affect the strength verification of the main load-bearing structure of the fuselage, it cannot be accurately obtained. The load-bearing characteristics of the internal structure of the fuselage ignore the strength verification of the cabin floor beams and related supporting structures. There are also some tests tha...
