Abstract

The invention relates to a switching device and a test system in an aircraft plug-in aircraft vibration test, belongs to the technical field of flight vibration tests, and solves the problems that anexisting switching device is single in design, time-consuming in installation and poor in transportability. The switching device comprises a switching main body and a T-shaped pin, the switching mainbody comprises a top plate, a connecting rib and a bottom plate, and the top plate is connected with the bottom plate through the connecting rib; the top plate is connected with the door-shaped tool;the bottom plate is provided with a lifting lug penetrating hole and a key groove, and the key groove and the lifting lug penetrating hole are arranged in a crossed mode. The lifting lug penetrating hole is used for installing a hanger lifting lug, and the key groove is used for containing the force bearing part of the T-shaped pin. The hanging frame is simple in structure, easy and convenient toinstall and flexible to use, and quick connection of the hanging frame and the door-shaped tool is achieved.

Description

technical field [0001] The invention relates to the technical field of flight vibration tests, in particular to an adapter device and a test system in the vibration test of an external aircraft mounted on an aircraft. Background technique [0002] Vibration test is an important part of aircraft mechanical environment test and reliability test. It is an effective means of simulating the actual use environment of test pieces in the laboratory, and it is also an effective method in product design and product performance evaluation. With the increasingly stringent requirements for product quality and reliability indicators, it is more and more important to more accurately reproduce the real use environment of the test piece in the laboratory. [0003] For the aircraft whose actual use environment is an on-hook environment, the traditional vibration mode and test method of clamping the specimen to excite vibration cannot well reproduce the environmental stress it bears in the act...
