摘    要:航空发动机转子结构特殊,在平衡机上无法达到工作转速,只能在低速下进行平衡,有时效果并不理想,在实际运行中仍会由于平衡问题导致振动异常。针对存在不平衡量偏大的某型航空发动机,利用三圆法并结合实际情况,对其结构进行改装,实现了风扇转子的本机平衡,有效降低了低压转子的振动水平,经试验验证表明改装合理,平衡方法有效。该方法对其他型号发动机的本机平衡有较大的借鉴意义。

关 键 词:本机平衡  低压转子  振动  三圆法  航空发动机

Abstract:The rotor structure of aeroengine is special,it can''t reach the working speed on the balancing machine,it can only be balanced at low speed,sometimes the effect is not ideal,and the vibration anomaly will still be caused by the balance problem in the actual operation. Aiming at a certain aeroengine with large unbalance,the structure of the aeroengine was modified by using the three-circle method and combining with the actual situation. The balance of the fan rotor was realized,and the vibration level of the low-pressure rotor was effectively reduced. The experimental results show that the modification is reasonable and the balance method is effective. This method can be used as a reference for the balance of other engines.
Keywords:local balancing  low-pressure rotor  vibration  three-circle method  aeroengine
