Multi-bench synchronous vibration test device and test method thereof

The invention discloses a multi-table synchronous vibration test device and a test method thereof.The device comprises a simple foundation, a support, a tool and more than two vibration tables, the appearance and specification of the tool are set to be an open cuboid container matched with a sample, and the tool is installed on the simple foundation through the support to be in a main body flying shape; the support is provided with replacement groups with more than two heights and volumes corresponding to various test directions of a sample, and can be detachably replaced between a simple foundation and a tool; each vibration table is positioned and connected to a simple foundation according to the excitation direction required by a sample test, is connected with the tool through a flexible rod, transmits excitation, and synchronously outputs high thrust and combined excitation to a sample. By applying the system, a plurality of vibration tables with various thrust forces are arranged and connected to form a
