04.1 - Material Issues, Fatigue and Damage Tolerance
THE EFFECT OF STRUCTURAL PARAMETERS OF AIRCRAFT PANEL ON VIBRATION FATIGUE LIFE
P. Liš, J. Maš; šAircraft strength research institute, China
The vibration fatigue problems widely exist among the aircraft shell structures, which can even lead to the skin tearing. We studied the vibration fatigue problem based on the theory of damage mechanics.rnconclution 1:When the reinforcement height parameter is 30mm, the vibration fatigue life is the highest.rnconclution 2:It is not recommended to use chemical milling in the panel structure.
