Abstract:

A numerical method of finding the steady-state response of the hull of a ship to a sinusoidal driving force is described. Results of calculations for the vertical flexural vibrations of the USS NIAGARA APA87 in response to a vertical driving force applied in the plane of the propeller are given and are compared with experimental data. It is also shown that the vibration of the hull at a frequency other than one of the natural-mode frequencies may be calculated as the sum of the vibrations of the natural modes compounded by a normalization process. In the Appendix a brief set of instructions is given which may be used for the computation of forced vibration. Author
