CALCULATED NATURAL VERTICAL HULL FREQUENCIES AND NORMAL MODES OF SURVEYING SHIP AGS 26

Abstract

The normal mode shapes, natural frequencies, and bending moment distribution of vertical flexural vibration of the hull were calculated for the AGS 26, a Surveying Ship. Parameters used in calculations with a digital computer are tabulated. The two-noded vertical natural frequency obtained with the computer agrees closely with that calculated using the Burrill empirical formula.
