The adapter tool is used for loading a product. The plurality of vibration tables are used for supporting the adapter tool and providing vibration for the adapter tool. Besides, the vibration test apparatusalso includes a plurality of hydraulic ball hinges that are connected to the surfaces of the plurality of vibration tables and support the adapter tool.

Description

technical field [0001] The present application relates to the aerospace field, in particular, to a vibration test device and a method for performing a vibration test on a product. Background technique [0002] Aerospace products will be subjected to harsh vibration dynamics environments during their life cycle, especially during launch and flight, which are mainly subjected to vibration dynamics environments caused by engines and aerodynamic turbulence, and they need to be assessed for their vibration environment adaptability. For now, the ground test is still an effective means and a necessary link in the development stage of aerospace products. With the continuous development of new launch vehicle technology, the diameter, weight and test level of the product are getting larger and larger, and the vibration test technology is proposed. challenge. [0003] At present, multiple parallel excitation vibration tests are used (multiple parallel excitation refers to the use of m...
