Abstract:

Vibration investigations consisting of mechanical impedance and decay rate studies were conducted on the modified USNUSL furnished CW 454 Sonar Dome at Boston Naval Shipyard prior to installation on the U.S.S. WITEK EDD 848. The surveys included impedance and decay rate measurements on the dome in air and in water, with and without ANSQS-23 transducer installed as well as decay rate measurements on the installed dome in drydock and at pierside. The results of the mechanical impedance survey show the transfer impedances to be very high for a structure of this type while the decay rate tests show no simple, direct correlaton between the in air to in water conditions except the increased damping for a submerged dome.
