摘　　要：论述了微动疲劳的概念及对其研究的必要性。对微动疲劳研究的4个主要部分即微动疲劳的机理研究、影响因素、寿命预测和防护方法的发展过程进行了论述,尤其对当前的研究现状及所取得的成果做了重点阐述,并说明了一些尚待研究的问题。从微动疲劳机理研究、研究方法和防护方法等几个方面概述了微动疲劳研究的发展趋势。The concept of fretting fatigue and the necessity of its research are stated. The development process about fretting fatigue research is expounded in four fields, the failure mechanism research, effecting factors, fretting fatigue life and the protection technique. In the basic research, the current research results about fretting mechanism and research progresses in fretting fatigue strength are introduced emphatically. The applications of several protection methods about the surface improvement technique, using new materials and the structural design changes, etc, in anti- fretting fatigue damage are put forward. Some problems that need to be further studied are illustrated. From several aspects, such as fretting fatigue mechanism research and protection methods, etc, the development trend about fretting fatigue research is generalized.
