Abstract

The disclosure provides a multifunctional fixture for vibration testing of aircraft storage tanks, and relates to the technical field of mechanical design. The multifunctional fixture includes a box body, a first mounting surface, a second mounting surface and a mounting ring, wherein: the box body has a cavity for accommodating the storage tank, the cavity passes through the first end and the second end of the box body, and the second One end has an opening for the storage tank to pass through, and the opening communicates with the cavity; the first mounting surface covers the second end and is fixedly connected with the second end for connecting with the vibrating table in the first direction; the second The installation surface is fixedly connected with the outer surface of the side wall of the box body, and is perpendicular to the first installation surface, and is used to connect with the vibrating table in a direction perpendicular to the first direction; the installation ring is arranged at the first end and the second end between, and surround the inner wall of the cavity, and can be detachably connected with the storage tank. The disclosed multifunctional fixture for the vibration test of the aircraft storage tank can reduce the test cost and improve the test efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of mechanical design, in particular to a multifunctional fixture for vibration testing of aircraft tanks. Background technique [0002] For aircraft containing liquid propellant storage tanks, the aircraft needs to experience harsh mechanical environments during transportation and flight. In order to ensure that the storage tanks do not fail during aircraft transportation and flight, vibration tests are usually used to assess filling Structural reliability of liquid rear tanks. [0003] During the transportation and flight of the aircraft, the installation state of the storage tank will change. For example: when the aircraft is transported horizontally, since the installation surface of the storage tank is parallel to the ground, the direction of gravity is vertical to the installation surface; while when the aircraft is flying vertically , the installation surface of the storage tank is perpendicu...
