Abstract: The related progress of vibration fatigue test at home and abroad is reviewed from the aspects of sample form, excitation mode, load type and determination of the load. Then, the failure mechanism, failure criterion of vibration fatigue, the estimation method for vibration fatigue life and the finite element model are reviewed. Finally, the problems and prospects of vibration fatigue in simulation models, composite materials and complex engineering environments are presented.
