Abstract:
The objective of the present work was the same as that of its predecessor that is, to demonstrate by analyses of experimental data that a postulated quadratic functional polynomial model is a reasonable representation of the added ship resistance produced by waves. In the course of the present work some improvements were made in the cross-bi-spectral analysis methods developed previously, three complete cross-bi-spectral analyses of experimental data were made, and it was shown that the mathematical model allows at least the very low frequency non-linear fluctuations of resistance to be synthesized in the time domain.
