Experimental and Numerical Study of the Wave Response of a Flexible Barge

摘要

The work presented here is a follow-up of a paper given at the previous conference (Malenica et al., 2003). A second series of experiments is described, conducted with a model consisting of twelve rigid units connected, at deck level, by a steel rod. Whereas, in the previous experiments, only vertical bending was allowed, in this new set of experiments, horizontal bending and torsion are permitted as well. Tests are conducted in regular and irregular waves of varying headings. Following the theoretical work presented in Ledoux et al. (2004a), new developments have been made, in the Diodore software of Principia, to include horizontal bending and torsional modes. Good agreement is obtained between numerical and experimental RAOs of the bending and torsional modes.
