摘要
本文简要介绍了结构稳定性理论和有限元屈曲分析理论,通过建立波纹管材料简化模型和有限元模型,对不同单元模型下的波纹管进行内、外压屈曲分析,并对结果与实验值进行了分析。
The structure stability theory and finite element buckling analysis theory are introduced. Through establishing simplified bellows material model and finite element model, bellows buckling under internal and external pressure is calculated with different element models. Finally,the analysis results are compared with the test results.
