보강 원통형 쉘에 탄성 지지된 기계류에 의한 수중 음향 방사
Acoustic radiation from resiliently mounted machinery in fluid loaded infinite cylindrical shell with periodic ring supports
초록
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.
