| 摘 要： | 对穿浪型双体船在波浪中航行时的受载状况进行研究,采用规则波理论计算其所受波浪外载荷。利用有限元法建立了铝合金穿浪双体船波激振动响应数值计算模型。基于水弹性理论,采用所建立的数值模型对某全铝合金穿浪双体船高海情试验进行了数值模拟,将数值模拟结果与实船试验数据进行了比较,证明本文方法可靠。进行了该船受6级海况波浪激励的振动响应计算,发现全铝合金穿浪双体船波激振动位移响应较大,远大于常规单体船。还发现高海情中航行时的波激振动应力响应值亦较大。

| Abstract: | The loads condition is studied for wave piercing catamarans(WPC)while it is operating in sea condition and the wave loads are calculated by applying regular wave theories.A three-dimensional finite element model of the whole ship is built up.Based on hydroelasticity theory,wave-induced vibration responses for aluminum alloy WPC are researched and the vibration analysis has been performed in the grade of 6 sea condition.The reliability of this method is confirmed by comparing its results with the test data i... |
