摘要
针对半潜船振动控制问题进行研究,分析总结半潜船船型特点及振动计算研究现状,阐述半潜船振动计算中重点关注的问题。梳理半潜船振动评估中主要关注的激励源,分别利用数值计算法以及有限元方法对半潜船总振动情况进行研究。对半潜船生活楼区域结构整体振动情况及局部板架振动情况进行研究,通过强迫振动分析的方式进行生活楼区域结构的响应分析,并根据计算结果进行结构的优化设计。研究结果可为后续工程实践中的半潜船振动评估及结构设计提供借鉴。
The issue of vibration control of semi-submersible ship is studied.The characteristics of semi-submersible ship and the research status of vibration calculation are summarized.The key problem in vibration calculation of semi-submersible are expounded,and the main excitation sources in vibration of semi-submersible ships are discussed.The numerical method and the finite element method are used to study the total vibration of semi-submersible ships.The total vibration of deckhouse structure and the local vibration of grillage is studied,and the response analysis of deckhouse structure is carried out by forced vibration,and according to the calculation results,the optimization scheme is determined.Research results can provide references for the subsequent vibration evaluation and structural design of semi-submersible ship.
