| 摘 要： | 针对高速穿浪双体船,应用两种不同的理论对其附连水质量进行计算;利用大型有限元计算软件Patran和Nastran建立了全船三维有限元模型,并分别计算和分析了该船的模态。结果表明对于穿浪双体船按这两种理论计算所得的结果相差很小,并与实船测试数据符合较好。

| Abstract: | The added mass of entrained water for the wave piercing catamarans was calculated by two different theoretical methods.A three-dimensional finite element model for the whole ship was established in Patran and the ship's modals were calculated in Nastran.The numerical results of the added mass showed that the values calculated by the two different methods have little discrepancy,and the results of modal have good agreement with the experimental data. |
