摘要
利用有限元软件ANSYS对外压容器进行特征值、非线性屈曲分析,求出特征值和非线性失稳临界载荷,给出关于外压容器稳定性的分析结论,为提高外压容器安全性和结构设计合理性提供依据。
The characteristic values and nonlinear buckling analysis is performed with ANYSYS,special finite element analysis software,for vessels subject to external pressure to obtain the critical load to loose the stability.The result of the stability analysis for vessels subject to external pressure is gained and used as the basis to improve the safety and structural suitability of external pressure-undertaking vessels.
