| 摘 要： | 通过有限元法对一艘40万吨矿砂船进行了全船和局部的振动性能预报。在预报过程中通过流固耦合方法添加附连水,用界面位移综合法进行局部模态分析,并用Holden法加载螺旋桨激励。计算中发现:因为主机未加横撑而引起的船体多处剧烈振动。最终提出了添加横撑的方案。该方案能使40万吨矿砂船振动性能改良,满足ISO6954标准。

| Abstract: | Based on Finite-element method,a study of global and local vibration of 400,000dwt ore carrier is performed in this paper.The research performs the added mass by using fluid-solid coupled method;adopts static condensed method to process component mode analysis;and carries on Holden method to load propeller induced pressure.The calculation results conclude that multiple spots of hull appear heavy vibration character due to the condition without main engine top bracing installation.Based on this conclusion,a ... |
