摘要
应用三维造型软件建立渤海湾宝华号滚装船的实体模型,再将模型导入有限元分析软件,解决了逼近真实船舶廓形的有限元模型建立的问题。应用Adina有限元分析软件对宝华号滚装船进行模态分析,得出了其横摇模态及模态频率范围。通过仿真得到的宝华号的流固耦合模态频率范围及其模态振型,有利于对滚装船上的装备及货物进行管理。
The solid model of Baohua Ro-Ro ship in Bohai Bay built in 3 D modeling software was then imported into Adina finite element analysis software. In this way, the problem that the FE model can not approach the actual profile of the ships was solved satisfactory. The modal analysis of the ship was performed in Adina. The rolling modes and the mo dal frequencies were obtained. The fluid-structure interaction modal frequency range and vibration mode of the Ro-Ro ship were also obtained. The numerical results were helpful to manage the equipment and cargoes on the ship.
