Abstract: A parametric study of the vertical free vibrations of a ship hull is presented. All the effects of the rotary inertia of mass, shear distortion, thrust force, shear lag, and various damping components are taken into account in analysis. The importance of these parameters to ship-hull vibrations is discussed. The method of calculating the overall damping ratios is included and particularly emphasized.
