Acoustic radiation from resiliently mounted machinery in fluid loaded infinite cylindrical shell with periodic ring supports

보강 원통형 쉘에 탄성 지지된 기계류에 의한 수중 음향 방사

Analytical model is derived for the far-field acoustic radiation from machinery installed inside cylindrical shell. The analytical model includes the effect of fluid loading and interactions between periodic ring supports. Transmitted force from machine to a shell can be different by the impedance of shell. In this paper the transmitted force from machinery to a infinite shell through vibration isolator is considered by the impedance of shell. The effect of the shell impedance for acoustic radiation is investigated.
