-
摘要: 从试样形式、激振方式、载荷类型与载荷确定等方面综述了振动疲劳实验的国内外相关进展,然后对振动疲劳的失效机理和失效判据进行总结评述,再对振动疲劳寿命估算方法和有限元模型归纳介绍,最后提出了振动疲劳在仿真模型、复合材料和复杂工程环境方面的问题及展望。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.
