EXPERIMENTAL PROGRAM FOR THE DETERMINATION OF HULL STRUCTURAL DAMPING COEFFICIENTS

This report outlines a program of full-scale and model experiments for the determination of hull damping coefficients. A scheme for the experimental isolation of the damping coefficients associated with each important mode of vibration is presented. The breakdown of the total damping into its separate components (structural, cargo, and hydrodynamics) and the determination of the distribution of the damping along the ship are examined. Excitation devices and analytical methods for reducing the experimental data are also discussed.
