A Study of Wave-Induced Vibrations : 1st report

概要

論文の詳細を見る
Wave-induced vibrations (springing) have been studied both theoretically and experimentally. The model experiments have been carried out using a tanker model of 7 meter length. Higher harmonic excitation in regular waves (which means the exciting force with the frequency multiple of the frequency of encounter) and the response to it have been confirmed both in theory and experiment. Also it has been shown that the natural frequency of the 2-noded hull vibration and the ship speed play an important role in the response of springing. The necessity of the future work is emphasized especially in the field of estimation of hydrodynamic exciting force in the region of short wave length, in order to refine the numerical accuracy.
