LNG储罐有限元静动力分析方法的探讨
|
摘要
目前,国内自主设计和建造LNG全容罐还存在很大的困难,有限元软件的发展给储罐的研究提供了有效的途径,但是,大型LNG储罐的有限元静动力分析在国内还相对较少,如何建立与实际工程相一致的有限元模型是一个关键问题。本文总结了部分前人对储罐构筑物结构的有限元静动力分析方法,并针对大型LNG全容罐自身的特点,对其有限元静动力分析方法做了探讨,最后提出了在模型建立中需要深入考虑的几个问题,给相关工程设计研究人员提供参考。
Currently,there are still lots of difficulties in independent design and construction of LNG full containment storage tank in China.The development of finite element software provides an effective way for research on storage tank.However,the work of finite element analysis of large LNG storage tank for static and dynamic in our country was also less than that in other countries.How to build the finite element model consistent with the actual project is a key issue.This paper summarized some of the previous storage tank structures on the static and dynamic finite element analysis methods.The static and dynamic finite element analysis methods of large-scale LNG storage tank were discussed combined with its characteristics.Finally several issues that need to be considered in depth when a model is built were proposed,which can provide references for engineering design and study.
