摘要
对近年来航空发动机整机动力学的研究现状、进展进行了综述,包括双转子系统固有特性计算、转子-滚动轴承系统动力学、转子叶片振动、发动机机匣动力学、机动飞行转子系统动力学、航空发动机转子碰摩动力学、航空发动机转子裂纹以及整机动力学等。最后对航空发动机整机动力学今后工作研究的方向进行了展望。
This paper provides an overview on the research of the dynamics of complete aero-engine systems in recent years.The review includes the calculation of the dynamic characteristics of dual-rotor systems,dynamics analysis of rotor-roller bearing systems,research on the vibration of rotor blades,analysis of the dynamic responses of the casing,the rotor-dynamics in maneuver flight,dynamics analysis of the rubbing of rotor-casing systems,dynamics of the cracked rotor systems,etc.Finally,discussions are made to propose certain directions for future research.
