Description

technical field [0001] The invention relates to a floor fatigue test device, in particular to an aircraft floor fatigue reliability test device, which is used in the fatigue test of civil aircraft interior parts. Background technique [0002] The floor of civil aviation aircraft will be damaged to varying degrees under the condition of long-term rolling by the dining car. The structural design of the aviation floor support frame and the selection of floor materials need to be accurately evaluated and tested in the early stage of design and development. Therefore, there is a need for a practical testing tool to directly reflect the load-resistance capacity of the aviation floor, so as to detect the quality of the floor. At present, domestic floor rolling durability equipment cannot realize the adjustment of loading and position, and cannot accurately evaluate the quality of floor durability. Contents of the invention [0003] The present invention proposes an aircraft floo...
