摘　　要：航空发动机作为飞行器最关键、最核心的部位,长期服役于高温、高载等极端环境,疲劳失效是导致发动机结构破坏的主要原因之一。随着工业的发展,发动机材料的超高周疲劳问题日益凸显。本文总结了发动机典型材料超高周疲劳关注领域的研究现状,对当前超高周疲劳试验技术的应用情况进行了阐述,包括超高周轴向振动疲劳、弯曲振动疲劳、扭转振动疲劳、复合振动疲劳等试验加载技术以及温度控制技术、损伤监测技术,并对我国航空发动机典型材料超高周疲劳试验技术的发展做出展望。As the most critical and core part of the aircraft,the aero-engine has been serving in extreme environ-ment such as high temperature and high load for a long time.Fatigue failure is one of the main causes of engine structure failure.With the development of industry,the problem of very high cycle fatigue(VHCF)of aero-engine materials becomes increasingly prominent.This paper summarizes the research status of VHCF of typical engine materials and describes the application situation of VHCF test technology.Including very high cycle axial vibration fatigue,bending vibration fatigue,torsional vibration fatigue,composite vibration fatigue test loading technology,temperature control technology and damage monitoring technology,the development of ultra-high cycle fatigue test technology for typical aero-engine materials in China is also prospected.
