项目摘要
載荷時の航洋双胴船の結合甲板には, 船体縦運動に寄因する波浪衝撃圧が頻繁に作用する. この波浪衝撃圧の大きさと時刻歴とを求めるために, 昨年度に引続き, 双胴船の構造モデルを用いた水面落下試験を実施した. その結果, 水面と接触する結合甲板の剛性と固有振動数の差異が結合甲板に作用する衝撃圧の地域的分布とその時刻歴とに及ぼす影響を定量的に求めることができた. これは, 従来の多くの研究者が用いた剛体に近いモデルによる水面落下試験からは求めることができなかった事項である.また, 衝撃圧が作用したときの結合甲板の構造応答を求めるために, 構造部材の弾性衝撃応答を解析する理論の精密化を行った. 即ち, 任意のアスペクト比, 任意の周辺条件の板部材に任意の地域的分布と時刻歴の衝撃圧が作用する場合について, 板部材の弾性衝撃応答を求める理論を開発した.双胴船の構造モデルを用いた水面落下試験から求められた衝撃圧の計測値(分布と時刻歴)をもとにして結合甲板の構造応答(撓みと歪の分布とそれらの時刻歴)を解析した. 解析値は実験値と極めて良好な相関を示している.
The double-carcass ship is connected with the deck ship during the load, and the movement of the hull is due to the noise effect of the wave wave. During the rush hour, we asked for a round of weather. Last year, the double-carcass ship was built to use a drop from the surface of the water to do the job. According to the results of the test, the surface contact temperature, the natural vibration number of the deck vibration, the difference of the natural vibration on the deck, the distribution of the temperature on the deck, the distribution of the temperature field, the temperature, the temperature, the temperature Please tell me that the researchers have used the body to get close to the surface of the water and to ask for help. In this paper, the effect of the equipment on the deck is analyzed, and the precision of the theory is analyzed. That is, the distribution of the board parts under any conditions, the distribution of the board parts, the distribution of the board The double-carcass ship is built with a drop on the surface of the water to ask for the test (distribution time). The double-carcass ship is built with a double-carcass ship and the double-carcass ship. The analysis shows that there is a good picture of each other.
