溢流式嵌镶圆管换能器的辐射声场仿真

s the effective low frequency sound sources, the free-flooded segmented ring transducers have very extensive use in underwater detection and underwater communication. Based on the finite element theory, the radiation sound field formed around the free-flooded ring have been simulated with ANSYS software, especially their two resonances and the vibration performance have been analyzed. The simulations show that the whole analysis procedure are quickly, simplely,intuitionistic and accurately. More further conclusion is that the finite element method has the universal applicability for the sound field analysis of the free-flooded ring and some other transdcuers, so it is one effective way in structural design, sound field simulation, and performance estimation.
