Abstract:

In this paper, the finite element model of a torsion tube universal joint assembly and supporting bearing of C919 is established. The modal analysis and sinusoidal analysis are carried out. The fatigue life calculation formula under sinusoidal vibration is deduced and the life of the model is predicted. The correctness of the model is verified by modal test. The correctness of the fatigue life calculation is verified by sinusoidal test. The fatigue life evaluation can be used to predict the sinusoidal vibration fatigue life of related models through sinusoidal test．
