Double-basin coupling three-dimensional acoustic elasticity test verification method for locally applying acoustic covering layer

The invention discloses a double-basin coupling three-dimensional acoustic elasticity test verification method for locally applying an acoustic covering layer, and relates to the technical field of test. The double-basin coupling three-dimensional acoustic elasticity test verification method manufactures a double-layer flat plate model of a real object corresponding to a double-basin coupling three-dimensional acoustic elastic model and carries out laying construction of a local acoustic covering layer to obtain a test model, and the test model can well reflect main acoustic vibration transmission characteristics brought by double-basin coupling and local laying. A batch of vibration acceleration sensors are arranged according to a dry modal test result of the test model, and then, the model can be arranged in a test water area to carry out a fluid-solid coupling vibration and underwater sound radiation test, thus effectively verifying the double-drainage-basin coupling three-dimensional acoustic elastic mode
