摘要
微动疲劳普遍存在于航空结构中,是研究的热点之一。结合某型机Ti1023主桨毂中央件抗微动疲劳的工程实践,介绍了微动疲劳机理、影响因素和防护技术,为缺口敏感型Ti1023材料在其他动部件推广应用提供有益借鉴。
Fretting fatigue that exists in the structure of aeronautics is ubiquitous,and has been a focus of the industry.Based on the anti-fretting fatigue experience of Ti1023 main rotor hub central part,this paper introduced the mechanism、influencing factor and anti-fretting fatigue technique of Ti1023,which would give the beneficial reference to other application.
