EXPERIMENTAL DETERMINATION OF PRESSURE AND STRAIN ON THE BOW SONAR DOME OF USS BARRY (DD 933),

Abstract

Measurements were made on the bow sonar dome of USS BARRY (DD 933) during full-scale trials to determine the pressure loadings on and structural response of the dome. These measurements are correlated with ship motions and sea states. The maximum stress measured in the dome structure was 13,500 psi, compression. The maximum pressure observed during the trials was 42 psi. Both the maximum pressure and the maximum stress occurred during a slam in a State 6 sea. In this sea condition acceleration at the bow reached =1.1 g, and the pitch was as high as =5 deg. From the measured strains in the hull, a maximum midships bending stress of 18,750 psi tension and a maximum quarterpoint shear stress of 3400 psi were determined. The measurements show the dome to be adequate to withstand the stresses resulting from all maneuvers conducted during the trials. (Author)
