title = "Fatigue life prediction of flap safety pins for civil aircraft",
abstract = "According to the requirements of airworthiness regulations, the safety pin of the flap support arm of a civil aircraft should bear the aerodynamic load of the aircraft wing under normal conditions, and at the same time, it also should be convenient for emergency disconnection to avoid damaging the overall oil tank of the wing and then causing greater accidents under emergency conditions. Therefore, accurate prediction of the fatigue life of the safety pin of the flap of a civil aircraft is of great significance to the operation and maintenance of the aircraft. For the safety pin of the flap support arm, the static tests were carried out first to determine the dangerous position and the ultimate strength of the flap support arm. Then the finite element analysis by Abaqus was carried out to obtain the nominal stress and stress concentration coefficient of the dangerous position. In addition to the prediction of fatigue life of the dangerous position was obtained by using the nominal stress method and the fatigue damage accumulation theory. Finally, the fatigue tests of the safety pin were conducted to verify the results of life prediction. The error between the fatigue test results and the results predicted by the nominal stress method is small, which conforms to the actual needs of the engineering.",
