Analysis of Fatigue Life in High Temperature of W Pattern Sealing Rings Used in Aircraft Engine

Abstract:

sealing rings used in aircraft engine are surrounded by high-temperature gas and cyclic loading when they are working. The reliability of its work directly affect flight safety and engines life. This paper framed some kind of W pattern sealing rings finite element models with different sectional structure size, first analyze them strength of structure in specific conditions, then simulate the fatigue life of them by using analysis methods of fatigue and parameters of fatigue test, finally we can get damage contours and fatigue life in high temperature of W pattern sealing rings theoretically, providing some theoretical reference of designing and manufacturing sealing rings.
