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。
Based on the analysis of the stability of the structural strength of the cockpit, the finite element analysis software NASTRAN is used to analyze the linear elastic finite element analysis of the cabin structure under the conditions of quasi-static loading and transient loading , And the elasto-plastic finite element analysis of the cabin structure under the transient “transient” loading condition.
