Conical pipe joints are widely used in pipeline systems of various aerospace vehicles, and the stability of their sealing performance directly impacts the reliability of the aircraft's operation. Engineering experience has shown that setting circular grooves on the conical surface can improve the stability of the sealing performance of conical pipe joints. However, there is currently a shortage of experimental data to support this viewpoint. This article takes a 74° conical pipe joint commonly used in aircraft engines as the object and demonstrates rotational bending fatigue tests that circular grooves can significantly improve the stability of the sealing performance of conical pipe joints under vibration condition. On this basis, this article verifies through finite element simulation that the edges of the annular groove can generate contact pressure concentration bands, which serve as a form of line sealing. Thus, a qualitative explanation is provided for the mechanism of improving the stability of sealing performance by the annular groove. This study provides a reference for improving the design of conical pipe joints and other forms of static sealing structures.
