Embodiment Construction
[0027] Describe the present invention below in conjunction with specific embodiment:
[0028] The horizontal test device used in the reliability test of the uplock of the aircraft landing gear door in this embodiment is composed of a connecting support structure, a simulated door structure, and a driving and loading structure.
[0029] The door uplock to be tested, the simulated door structure and the driving loading structure are all installed on the connection support structure, and the connection support structure is also the connection interface with the external vibration test bench. The installation method of the hatch lock to be tested is consistent with the real situation. The simulated cabin door structure is used to simulate the motion trajectory of the lock ring of the cabin door, so that the motion trajectory of the lock ring in the test device is consistent with the motion trajectory of the lock ring required by the test cabin door lock. The driving and loading s...
