Abstract
Forced oscillation tests are carried out with a segmented shipmodel to investigate the distribution of the hydrodynamic forces along the hull for heaving and pitching motions.
The vertical forces on each of the seven sections of the shipmodel are measured as a function of forward speed and frequency. By using the in-phase and quadrature components of these forces, an analysis is made of their distribution along the length of the shipmodel.
The experimental results are compared with the results of a simple strip theory, taking into account the effect of forward speed.
The comparison shows a satisfactory agreement between theory and experiment.
