Description

technical field

[0001] The invention relates to the technical field of standard component testing, in particular to a vibration testing device and testing method for aircraft panel connectors. Background technique

[0002] Aircraft panels and covers are parts used to realize the connection of structural components, quick opening of internal structures and decoration on aircraft. Typical aircraft panels and covers are connected by bolts and nuts, quick-release locks and other connectors. Typical aircraft panel structures are composed of upper interlayers, lower interlayers, and aircraft panel or cover connectors.

[0003] The vibration test is to simulate the object or model in the laboratory to assess the vibration resistance performance under actual working conditions. Through the vibration assessment of the aircraft panel or the connector assembly of the flap, it is possible to simulate the actual working condition of the assembly, that is, under the condition of constant...
