船体波激振动共振频率的计算方法

Calculation method of resonant frequency on wave-induced shiphull vibration

针对大型及超大型船舶，从水弹性理论出发，对船体波激振动共振频率的计算进行了研究，给出了迭代求解公式，编制了相应的计算程序，并进行了实例计算，取得了一些有价值的结果．研究表明，对大型及超大型船舶，应考虑波浪影响计算船体波激振动共振频率．

A method is developed for calculating resonant frequency of wave-induced shiphullvibration to large ship according to the hydroelasticity theory,and an iterative computer programis compiled.By the practical example calculation,some valuable results are achieved.Thecalculated results show that the wave effect should be considered to determine resonant frequencyof wave-induced shiphull vibration of large ship.
