摘　　要：基于流固耦合理论对采用刘易斯方法求得的船体总振动固有频率进行了修正,给出了修正系数,并且对流固耦合计算中流体单元范围的选取进行了计算和讨论,可提高船体总振动预报的效率和准确度。Based on the theory of fluid-structure coupling, this paper amends the natural frequency of overall vibration obtained by the Lewis method and the correction coefficient is given. Moreover, the selection of fluid range in fluid-structure coupling calculation is calculated and discussed. Thus, the efficiency and accuracy of overall vibration forecast can be increased.
