摘　　要：近年来,海运行业对集装箱船的需求量逐渐增加,随着集装箱船主尺度的不断增加和快速性的不断提升,船体总强度下降并且会发生高频振动,这些共同导致了船舶的水弹性响应。有鉴于此,本文基于AnsysFluent和TransientStructure,使用CFD-FEM单向耦合的方法,研究波浪因素对集装箱船的水弹性响应,对Fr=0.26时不同波浪情况下KCS船的水弹性响应进行仿真,结果表明,波浪情况下KCS船呈现周期性响应,主要受船舶固有频率影响,船舶会出现周期性的中拱现象。With the continuous increase of the size of container ship owners and the continuous improvement of rapid-ity,the total strength of the hull decreases and high-frequency vibration occurs,which together lead to the hydroelastic re-sponse of the ship.In view of this,based on Ansys,Fluent and Transient Structure,this paper used the unidirectional coup-ling method ofCFD-FEM to study the hydroelastic response of wave factors to container ships,and simulated the hydroelast-ic response of KCS ships under different wave conditions when Fr-0.26.The results mainly show that the KCS ship presents a periodic response under the wave condition,and the ship will have a periodic mid-arch phenomenon mainly affected by the natural frequency of the ship.
