Tonpilz Transducer Array for Sonar Systems

Application ID: 55891

This model sets up a linear array of nine tonpilz piezoelectric transducers in a 3x3 grid. A voltage is applied that includes a phase change across the three rows. The transducers are located in a box below the sea surface.

The exterior acoustics are modeled using the Pressure Acoustics, Boundary Elements interface, which is coupled to the vibrating structures with the Acoustic-Structure Boundary multiphysics coupling. This results in a hybrid BEM-FEM model of the full system.

There are two versions of the model:

  1. In the first, the exterior radiated field is calculated and visualized

  2. In the second, a simple scattering object is placed roughly 12 wavelengths away from the transducers; the resulting sound field is modeled and visualized
    • Model file: tonpilz_transducer_array_scattering_53a.mph

This model example illustrates applications of this type that would nominally be built using the following products:
