摘要
应用有限元分析软件对在渤海湾海域运营的滚装船进行模态分析,得到船体的横摇模态及模态频率范围。根据这些系统固有特性数据,提出一种减摇装置的构建方法。应用调谐质量阻尼器被动减振的原理,利用滚装船上的装备及货物作为减振质量体,使用弹簧和阻尼器连接减振质量体和船体,构成减摇装置,实现滚装船的横摇控制。通过合理选取减摇装置的参数,提高了横摇控制效果。仿真分析结果表明:减摇装置对滚装船具有较好的横摇控制效果。
The modal analysis of Baohua ro-ro ship in Bohai Bay is performed in this paper using Adina finite element analysis software.The rolling modes and the modal frequencies are obtained by the analysis.A construction method is proposed for an anti-rolling device of ro-ro ships,where the use of the idea of tuned mass damper is made.The cargoes on the ship are used for the mass body of the anti-rolling device,which are connected to the deck or hull of the ship by means of springs and dampers.In order to increase the control effects,the reasonable selection of parameters must be made.The simulation results indicate that good rolling control effects have been achieved.
