摘要
文章采用三维有限元分析技术对某半潜船甲板室局部振动情况进行模态分析预报,并结合本船主要相关激励源频率错开要求与半潜船型自身的结构布置特点,对甲板室结构进行设计研究,降低了本船甲板室局部振动风险。文章为类似船型甲板室结构动力学设计提供了基本流程与设计方法。
The paper studies the deck house local vibration mode analysis of ultra-large semi-submersible heavy lift vessel combined with the method of vibration excitation sources and the self arrangement characteristics by use of three dimensional FEM. The paper is to investigate the deck house vibration design techniques for initial design, and lower the vibration risk during the design phase. The paper provides a basic process and design method for the similar deckhouse structure dynamic design.
