摘要
基于ANSYS Workbench仿真平台对船舶的干湿模态进行有限元分析。针对一艘686TEU多用途集装箱船,运用船舶建模软件建立该船三维简化模型,将模型导入仿真平台并进行船体模态特性分析。数值计算结果表明,应用Workbench平台采用流固耦合方法能够计算大型结构的模态,验证了在Workbench中使用流固耦合方法计算船舶振动干湿模态的可行性。
In this paper, dry and wet modal vibration of a ship is studied by finite element analysis based on the Ansys Workbench simulation platform. Then, the three-dimensional model of a 686 TEU multipurpose container ship is established by a ship modeling software. The model is introduced into the simulation platform to analyze the modal performance of a ship. Numerical calculation results show that the Workbench platform can be used to calculate the large structure mode by the fluid-structure coupling method and that it is feasible to use the fluid- structure coupling method to calculate the dry and wet modes of ship vibration in Workbench.
