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 of CFD-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.
