摘要:
A method and procedure of high cycle fatigue life prediction for helicopter transmission system tail gearbox casing ispresented, including fatigue test load, three parameters S-N curve, reduction factor and cumulative damage law. According to thefatigue test results, the design load spectrum and the three parameters S-N curve, a fatigue life prediction of the tail gearboxcasing of a helicopter is performed as an example.
