摘要
综述了工程结构振动疲劳问题.首先从工程中存在的结构振动疲劳现象出发,论述了开展结构振动疲劳研究的重大意义,并对结构振动疲劳的定义及特点进行了详细的阐述;而后从结构振动疲劳寿命分析和结构疲劳损伤的振动诊断两方面回顾了结构振动疲劳研究的国内外现状,同时介绍了有关结构振动疲劳耦合分析的研究进展;最后讨论了目前研究存在的一些问题及今后的研究方向.
Problems of vibration fatigue in engineering structure were reviewed. Firstly, significance of research on vibration fatigue was expounded based on the phenomena about structural vibration fatigue in engineering, and the definition and features of vibration fatigue were elaborated. Then, research on the development of vibration fatigue life analysis and vibration diagnostic based structure fatigue at home and abroad were reviewed. Achievements on coupling effect of vibration fatigue were introduced at the same time. At last, some opening issues at present and new topics of this field in future were put forward.
