| 摘 要： | 大中型立式真空低温容器外下封头与支座连接处局部受力情况复杂,该处结构强度关系设备的强度是否可靠,目前通常是参考规范并主要靠经验来确定外下封头厚度,其结果相对较保守.针对外下封头受力特点,设计了一种新型加强结构,以150 m3液氩立式低温储罐为例,通过有限元分析对比和校核,表明该结构改善受力和优化结构效果明显,结构强度满...

| Abstract: | The stress distribution at the joint of lower closure and supports of medium and large diameter vertical vacuum cryogenic vessel is complicated.The strength of the joint is related to the safety of the vessel.Currently,it is general to determine the thickness of the closure by experience.The result may be conservative.With respect to the structural feature of this closure,in this article,a new reinforcing structure was designed.Exampled with 150 m3 vertical cryogenic liquid argon container,through the analy... |
