Vibration fatigue analytical and experimental research on typical titanium alloy panel in thermal environment
Vibration and thermal environments have been key factors that influence the safety of aircraft structure.The combined effect of these two factors causes fatigue damage to the aircraft structure more easily.This paper studies different structure types,including stiffened panel and honeycomb.Vibration properties,fatigue life,and damage location of titanium alloy panels with different thicknesses,bar spacings,and connection types are studied by the methods of analysis and experiment.For stiffened panel,damage occurs at fillet or corner plate.Honeycomb panel gets no damage in eight hours of experiment.Panels'thicknesses,bar spacings,and connection types have a small effect on their vibration fatigue life.
