STERN AREA VIBRATION MEASUREMENTS ON USS OBSERVATION ISLAND (EAG 154)

Abstract

Ide tifiers: Polaris, AG 154, EAG 153, Gopher Mariner, Old Colony Mariner. In establishing hull vibration characteristics of th Mariner-C L S HULL, FULL-SCAL VIBRA ION TRIALS RE CO DUCTED ON USS Observation Island (EAG 154). Vertical, athwartships, and fore-aft vibrations were measured at er under c lm and roug -water conditions The principal components of observed vibrations were at propeller bl de (4th order a d double blade (8th order) FREQUENCIES. T principal ull mod frequencies observed on the EAG 154 are compared with previous oretic l and xperimental results reported on SS G OPHER M ARI R, SS Old Colony ri r US C OMP SS Island (EAG 153). Good correlation exists between the experimental results observed on the EAG 154 a d the calcul te tural frequ ci ( uthor
