矿用救生舱的弹塑性有限元分析

摘要

通过分析救生舱舱体结构板格强度的稳定性，利用有限元分析软件NASTRAN，讨论了准静态加载和瞬态“一过性”加载两种情况下舱体结构的线弹性有限元分析，及舱体结构在瞬态“一过性”加载状态下的弹塑性有限元分析。%The paper analyzed the strength stability of flame of mine emergency refuge chamber, and use NASTRAN to carry out the linear elastic FEA of the flame at the standard static loading and transient loading mode. In addition, it conducted the elastoplastic FEA of the frame at the transient loading mode.
