  • The number of specimen in low cycle fatigue test of aero-engine component is small,making it difficult to confirm the reliable life.On the basis of before-mentioned circs,the factors affecting the component low cycle fatigue life were investigated.A new type of method combining with simulated specimen and tests of a few components was researched to evaluate the real component life and reliability.With this method,simulated specimen of 1st compressor disk slot of aero-engine was designed and low cycle fatigue life was assessed.The result shows that,the experimental simulation technology of low cycle fatigue life and reliability provides a new method for evaluation of life and reliability in real aero-engine component.
