航空发动机柔性转子动平衡方法

Study of Balancing Method of Aero-engine Flexible Rotors

根据航空发动机柔性转子现场动平衡实践的需要,建立向前和向后正交的柔性转子混合平衡法和平衡步骤,分别在模拟转子和真实转子对方法的可行性和有效性进行实验考核。结果表明,向前和向后正交的柔性转子混合平衡法,可有效对发动机转子实施高速动平衡,且可提高平衡效率、减少试重个数和开车次数。

A forward-and-backward orthogonal unified-balancing method of flexible rotors is established according to the in-situ balancing of aero-engine＇ s flexible rotors. Experimental investigations of the balancing effectiveness of this method are carried out. It is shown that the method is effective to balance the flexible rotors of the aero-engine, and have the advantages to improve the efficiency of the testing and reduce the number of the test weights.
