Abstract:

A comprehensive study was made of the derivation of equations for digital and electrical-analog solution of the natural frequencies and mode shapes of a ships hull idealized as an elastic beam. Effects of bending, shear, rotary inertia, coupled torsion and bending, initial curvature of the elastic axis, applied forces and torques, sprung masses, and other inertias are included. The calculation of the physical parameters from ship plans is described, and the accuracy of the results obtained by digital and analog solution is discussed. Author
