摘　　要：微动疲劳广泛存在于航空航天等各种机械构件中,加速构件接触表面及表层裂纹的萌生与扩展,微动是导致构件多裂纹损伤的主要原因之一。由于海军飞机服役环境的复杂性,铝合金构件腐蚀相当严重,腐蚀对航空铝合金材料微动疲劳的影响是研究微动疲劳时要考虑的重要因素。总结了国内外铝合金微动疲劳研究现状,阐述了研究存在的主要问题,对飞机构件铝合金材料微动疲劳的研究进行了展望。Fretting fatigue usually occurs in the structure of aeronautics and astronautics,and accelerates the generation and expansion of cracks on the surface of structures.Because of the complexity of the surrounding of aircrafts,the corrosion of aluminum alloy structures is quite serious,so research of corrosion influence on fretting fatigue is very important.Domestic and foreign studies of aluminum alloy fretting fatigue were summarized.The main existing problems of the study were discussed.Further studes of aluminum alloy fretting fatigue in aircraft structure were prospected.
