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 Ansys Fluent 和Transient Structure，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 rapidity, the total strength of the hull decreases and high-frequency vibration occurs, which together lead to the hydroelastic response of the ship. In view of this, based on Ansys, Fluent and Transient Structure, this paper used the unidirectional coupling method of CFD-FEM to study the hydroelastic response of wave factors to container ships, and simulated the hydroelastic 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.
