Abstract:

Measurements of the sound radiation patterns in water from the flexural vibrations of a clamped-edge steel disk have been made and are compared with the results of theoretical calculations for the two lowest order circularly symmetric modes of disk vibration. Although some differences were expected and were found due to the experimental condition which only approximated the assumptions made in the theory, it was found that the major features of the measured patterns agreed reasonably well with the theoretical patterns. The results have applicability to the design of sound source which could be used in underwater tracking of vehicles on a test range.
