Problems solved by technology

The national military standard GJB150A pointed out that it is inappropriate to rigidly connect the airborne external accessories directly to the vibration table. Due to the influence of the reaction, there will be great distortion in the test.

Abstract

The invention provides a supporting system for a vibration test of on-board add-on pieces and a design method thereof. The supporting system includes a structural supporting piece composed of a big girder and a counter weight, a hanger switching device and a free suspension device, wherein the hanger switching device is connected to the big girder of the structural supporting piece and a hanger for supporting an add-on piece separately, and used for indirectly installing the add-on piece on the structural supporting piece; the free suspension device is connected to the structural supporting piece, and used for suspending a combination of the structural supporting piece, the hanger switching device, the hanger and the add-on piece in a free simulation state. According to the supporting system for the vibration test of the on-board add-on pieces and the design method thereof, by utilizing the structural supporting piece, the dynamical coupling effect of add-on piece installation on an airplane is stimulated; by adopting actual boundary stimulation to conduct an on-hook vibration ground test of the add-on pieces, the dynamic strength of the add-on pieces can be effectively tested, and the boarding safety of the add-on pieces can be ensured.

Description

technical field [0001] The invention relates to the field of aviation tests, and more particularly relates to a support system and a design method thereof for vibration tests of airborne external parts. Background technique [0002] For airborne accessories, they are subjected to vibration transmission and aerodynamic forces of the aircraft during flight, and will withstand a certain vibration environment, which will affect their structural strength. In order to ensure the safety and reliability of the product, it is necessary to carry out the on-hook vibration environment test and assessment for the products suspended on the aircraft. If the real ground simulation test is passed, the product can be effectively assessed to ensure that it will not be damaged during use, thereby ensuring that the product has sufficient dynamic strength. [0003] After the airborne pendant is suspended on the aircraft, its dynamic characteristics will change due to the influence of the aircraf...
