PZT4 spherical shell-typed hydrophone simulation using a coupled FE-BE method

결합형 유한요소-경계요소기법을 사용한 PZT4 구형 쉘 형태의 히드로폰 시뮬레이션

This paper describes the application of a coupled finite element-boundary element method to obtain the steady-state response of a hydrophone. The particular structure considered is a flooded piezoelectric spherical shell. The hydrophone is three-dimensionally simulated to transduce an incident plane acoustic pressure onto the outer surface of the sonar spherical shell to electrical potentials on inner and outer surfaces of the shell. The acoustic field formed from the scattered sound pressure is also simulated. And the displacement of the shell caused by the externally incident acosutic pressure is shown in temporal motion. The coupled FE-BE method is described in detail.
