10000 m3真空球罐的外压稳定性分析

摘要

通过对10000 m3真空球罐光壳和带加强肋不同方案的外压稳定性分析，结合经济性对比分析，确定10000 m3真空球罐球壳结构采用光壳结构；阐述了该球罐的外压工况的有限元分析结果。%By analyzing the stability of external pressure of the 10000 m3 vacuum spherical tank without strengthening ribs and with different strengthening ribs,then comparing with the expense of the different constructions,reaching a conclusion that designing a 10000 m3 vacuum spherical tank without stiffening ribs is a better plan than designing with ribs;elaborating finite element analysis results of external pressure of this spherical tank.
