Abstract: In this paper, the axial beam suppression characteristics of acoustic barrier plate for cylindrical transducer are introduced. The model of cylindrical transducer with an axial barrier in water is established by using finite element simulation method. By changing the diameter of the baffle and its relative distance away from the cylindrical transducer, the suppression effect of the baffle on the axial beam of the cylindrical transducer is discussed. And the cylindrical transducer with an axial barrier plate has been developed. It is shown that the results of FEM simulation are in good agreement with the test results, and that the axial acoustic pressure of cylindrical transducer can be effectively suppressed by using barrier technique.
