摘要
上层建筑是船舶的重要组成部分,它所产生的有害振动会影响到船舶的安全,文章首先简要介绍了船体上层建筑振动的计算方法,然后建立了29 800 DWT散货船上层建筑的有限元模型,并采用不同网格密度进行了该结构的模态分析。计算结果和结论可为船舶上层建筑的可靠性设计方面提供参考。
Superstructure is an important part of the whole ship and its harmful vibration affects the safety of the ship. In this paper, the vibration calculation methods of the superstructure are introduced briefly. Then the finite element model of 29 800 DWT bulk carrier＇s superstructure is established and the mode analyses with different mesh density are made. The results and conclusions can be the reference in reliability design of the superstructure.
