ABSTRACT
This paper presents an experimental investigation of hydroelastic responses in heading regular wave. A 1:55 scaled segmented ship model is made to meet elastic similarity condition by using ten segments and two backbones. The vertical bending moments and shearing forces are measured by using load cells located on several sections. Furthermore, pitch and heave motions are measured by gyroscope situated at the center of gravity. Band-pass filter and power spectral density method is adopted to analyze hydroelasic responses. In conclusion, the influences of wave length and hull girder stiffness on hydroelastic responses are discussed. Springing phenomena occur in the small wavelength. In addition, the reduction of hull girder stiffness leads to the occurrence of springing easily.
