DAMPING VALUES OF NAVAL SHIPS FROM IMPULSE LOADINGS

The analysis of transient vibrations on naval ships is a useful means in the evaluation of a ships vibration characteristics. This report presents data of frequencies and damping obtained for four surface ships with a brief description of the analysis technique used. Anchor drops were used to excite transient vibrations of the ships hull at low frequencies. Damping values thus obtained are compared with previous findings.
