摘　　要：讨论了航空发动机扭转振动测量的特点及其对测量系统的要求,提出一种基于激光多普勒原理的新型航空发动机转子扭转振动测量方法,并分析了影响该方法测量精度的因素、测量范围,实验结果表明该测量方法能满足航空发动机转子扭转振动测量的要求。The characteristics of torsional vibration of rotor of aerobatic machine as well as requests for a measuring system is discussed. A new method of torsional vibration of aeroengine rotor based on laser Doppler principle is put forward. Several affecting factors of measuring precision and the measuring range of this method are analyzed. In order to prove the availability of this method, the experimental platform to obtain the result of experiment is set up, the result of experiment shows that this method meets the requests of torsional vibration measurement of aerobatic rotor.
