The acoustic levitation has been verified by many experiments.However,some complex structures coupled with the piezo-solid-fluid are difficult to get the analytical solution.The carrying capacity has been calculated by Ansys and has been tested by the experiment.The mathematical mode with 2D axi-symmetric which is coupled with piezo-solid-fluid could reduce the caculating time,improve the accuracy of results and ignore some mode shpe of non-axisymmetric.It is helpful to investgate the phenomenon of acoustic...
