## Finite element analysis of O-ring seal structure

• 摘要: 建立固体火箭发动机的橡胶O形圈的二维轴对称模型,采用非线性有限元方法计算了O形橡胶圈在库存和工作状态的变形及应力,分析了上下法兰张开间隙、初始压缩量、密封槽口及槽底倒角半径、密封槽宽、密封圈材料、O形圈截面尺寸及工作温度等典型参数对密封性能的影响:上下法兰张开间隙、密封圈的初始压缩率、密封圈材料等典型参数对最大接触压应力影响较大,而密封槽槽口和槽底处倒角对剪切应力影响明显.这些分析为密封结构的优化设计打下了基础;同时探讨O形圈应力分布规律,确定密封圈易受损和失效关键部位,初步确立了固体火箭发动机密封失效准则和失效模式.
