NOISE RADIATION FROM SUBMARINE HULLS. PART II. COMPARISON OF THEORETICAL RESULTS WITH MODEL TEST DATA MEASUREMENTS
Abstract
The design and instru e tion of a suitable model for investigating the vibration and sound radiation from a hull with a symmetrical foundation are described. The test results are explained, and in some respects successfully correlated with the predicted values. Natural frequenci s in air and water of the ring stiffened cylindrical model are in good agreement with the theory. Driving point impedance phase measurements conform o theory. For reasons which are discussed in detail, correlation of theoretical and measured far field sound pressures, for a 1-lb shaking force applied to the foundation, is fair only, and not as good as for the full-scale data obtained earlier. Longitudinal vibrations of a spheroidal shell are also discussed. (Author)
