The invention provides an aircraft structure and a crashworthiness analysis method thereof. The aircraft structure comprises a skin, a bulkhead, a passenger cabin floor, a cross beam, a longitudinal beam and a supporting piece. The skin is arc-shaped, the bulkhead extends along the bending direction of the skin, the cross beam is connected with two ends of the bulkhead, the passenger cabin floor is arranged on the cross beam, and the longitudinal beam is connected with the cross beam; the upper supporting plate is installed at the end, close to the longitudinal beam, of the supporting piece, the lower supporting plate is installed at the end, close to the skin, of the supporting piece, the hinging piece comprises the upper hinging piece and the lower hinging piece, the upper supporting plate is hinged to the longitudinal beam through the upper hinging piece, and the lower supporting plate is hinged to the skin through the lower hinging piece. The aircraft structure is simple in structure, the crashworthiness of an aircraft is enhanced, the aircraft can be gradually damaged in a falling collision accident, and the stability of the crushing process is guaranteed.
Description
technical field [0001] The invention relates to the technical field of fuselage structures, in particular to an aircraft structure and a crashworthiness analysis method thereof. Background technique [0002] Aircraft such as rotorcraft, helicopters, and large and medium-sized civil aircraft have become an indispensable part of people's daily life. Researchers have conducted a lot of research on the structural design of aircraft, and relevant institutions have also formulated relevant regulations on aircraft safety and lightweight design. Airworthiness Regulations. With the gradual maturity of aviation manufacturing technology and the gradual application of advanced composite materials, higher requirements are put forward for the structural design of aircraft. [0003] The fuselage structure is an important part of an aircraft. The fuselage structure not only bears the weight of its own structure such as wings, empennages, and landing gear, but also bears external loads such...
