FUNDAMENTAL STUDIES ON UNDERWATER SOUND RADIATED FROM A VIBRATING SHIP HULL, 6TH REPORT: AN EXPERIMENTAL EXAMPLE

The authors describe an experiment conducted to study the acoustic radiation problem in relation to a two-dimensional fully submerged circular cylindrical shell, and compare the results with theoretical solutions calculated in work reported upon earlier. The cylinder model was separated into three parts to exclude three-dimensional effects and an exciter was placed in the middle section, which was watertight. A clear vibrational mode for the cylinder was obtained in the low frequency experiment and radiational sound pressure was accurately measured. Prior to the experiment in an anechoic tank, the vibration experiment was carried out in air, verifying the eigenfrequency and shape of the vibration mode.
