- 中文摘要: 本文以頻率函數作數值分析,探討波浪中兩條船在線性彈性物連結下,其運動所受到的影響,整體的目標乃在於尋找一合理方法以減少橫搖及相對運動。文中以積分方程式之方法來解干擾的合成勢流,並考慮到不同之波向,船距及彈性係數。數值分析結果顯示單獨以彈性連結物並無法達到減低運動之效果,反而有加大之現象。因此文中建議應再加輔助物,如置護舷料於兩船間並以時間函數來作分析。
- 英文摘要: The paper presents a frequency domain method and numerical analysis of the hydrodynamicallycoupled motion on two elastically connected ships that are in close parallel position in oblique seas. Theoverall goal is to develop a technique to determine the critical sea state for safe cargo transfer between twomoored ships in the ocean. The paper is part of a preliminary study. The strip method has been found tobe a useful technique to analyze the hydrodynamically coupled motions of two parallel ships in obliquewaves. The present study is an extension of the foregoing to evaluate the effect of an idealized mooring onthe hydrodynamically coupled motions of vessels. The effects of the transverse hull clearance, wave head-ings and the stiffness of the connections were studied. The results show that there is a significant andundesirable increase in the rolling motion due to the existence of the connection. Another technique isrecommended:to include fenders between the two hull walls and analyze these effects in the time domain.
