摘　　要：采用有限元软件建立了橡胶类O形密封圈轴对称有限元分析模型,对2种不同安装方式下的密封圈应力应变分布进行了分析比较。研究分析了O形密封圈在不同压缩率和不同载荷下的应力应变,通过有限元软件得出了不同压缩率和载荷下的应力应变云图。通过对密封圈不同应力应变云图的对比分析,得出了密封圈与压缩率和载荷之间的密封规律。通过密封结构的有限元分析,对密封件的设计安装具有一定理论参考价值。The finite element analysis model of rubber O-ring is established by the finite element software. Two different installation mode of stress and strain distribution of the seal ring are analyzed and compared. Analyses the stress and strain of O-ring under different loads and different compression ratios. The stress and strain under different compression ratios and loads are calculated by finite element software. The regularity of seal between compression ratio and load is obtained by the analysis and contrast to different stress and strain contours. The sealing structure finite element analysis can do certain theoretical reference value to the design and installation of the seals.
