| 摘 要： | 该文给出了三维水弹性力学中弹性模态位移振型归一化时广义质量的计算方法，并应用三维有限元方法计算了箱式大型浮体结构的固有频率和广质量，经与均匀梁解析解的比较表明，两种方法差异不大，因此，采用均匀染解析解来计算这种结构的固有频率和广义质量是完全可行的，简化了计算工作。

| Abstract: | This paper presents a solution of generalized mass with the flexible displacement mode normalized as unit in three dimensional hydroelastic mechanics.Natural frequency and generalized mass of box shaped very large floating structures(VLFS)are calculated by using finite element method(FEM),and compared with that worked out by analytical method of uniform beam.It shows that the differences between two results are quite small,therefore it is appropriate to calculate natural frequency and generalized mass of box shaped VLFS with the analytical method of uniform beam. |
