| Summary: | Approved for public release: Distribution is unlimited === Random Decrement (RANDEC) Analysis was applied to time histories of roll motion for the Spruance class
destroyer. The data was generated from sea trials conducted on a ship in 1987. The RANDEC process was applied
to obtain estimates of roll- resonance modal damping and frequencies due to ship motion excitation by random-natured
hydrodynamic forces and moments. Prior to applying the RANDEC technique to ship data, a numerical algorithm was
developed and validated using reference data sets with known dynamic traits approaching that expected of the ship. |
