- Abstract
In order to more accurately assess the fatigue life of aero-engine hydraulic pipelines, a fatigue life prediction model was proposed. This model focused on calculating the damage to the hydraulic pipeline caused by the load in a cycle. On this basis, the analytical relationship between the stress at the dangerous point and the fatigue life of the hydraulic pipeline was established. The model was used to calculate the fatigue life of a certain type of aero-engine external hydraulic pipeline, and the theoretical calculation results were compared with the finite element simulation results. Thereby the effectiveness of the fatigue life prediction model is verified.
