EXPERIMENTAL DAMPING MEASUREMENT TECHNIQUES AND RESULTS BOTH IN AIR AND WATER

The addition of damping materials to the self-noise generated by vibration has been done for years at great expense to the Navy. In this study, several measurement techniques and the various drawbacks and errors method are considered. It is shown that the increase in the damping effectiveness or damping coefficient was much less in water than in air. The test technique allows measurements on normal structures to determine just how much vibration attenuation is obtained.
