The Effect of Strut Shape on Swath Ship Motion.

Abstract

Three different strut shapes were investigated to determine the effect of shape on the heave motion of SWATH ships at heave resonance. A time-domain analysis was developed to include the nonlinear effect of large motion amplitude. A two-dimensional model, in which the ship forward speed is assumed to be zero, was investigated to simplify the problem. The results show that a proper choice of strut shape can reduce the ship heave motion substantially at resonance. Keywords: Small-waterplane-area twin-hull (SWATH) sections.
