摘要
介绍了导管架平台有限元动力分析的过程。基于大型通用有限元程序MSC/NASTRAN,对导管架平台结构的动力学特性进行了有限元分析,得到了平台的自由振动特性和结构的动力响应,对导管架平台的设计、建造和安全评估有着一定的参考价值。
This paper introduces the dynamic analysis for jacket platform using the finite element method. By using large scale finite element analysis software MSC/nastran, it analysis the vibration characteristics and the transient respone of the jacket platform and draws related conclusions, which may be used as a good reference in the analysis and safety evaluation of the jacket offshore platform.
