摘　　要：某涡桨发动机低压模拟转子的工作转速在弯曲临界转速以下,该转子出现了由不平衡引起振动超限,导致无法运行至工作转速的问题,本文针对上述问题进行动平衡试验研究。首先,在动平衡机上对低压模拟转子进行低速平衡,再结合柔性转子高速动平衡技术,在高速旋转试验器上完成了低压模拟转子的高速动平衡试验,动平衡试验后的转子振动明显降低,表现出了良好的振动特性,平衡效果显著。本文的研究为控制高转速下同类型航空发动机转子的振动提供了一种有效的途径,具有重要的工程应用价值。The working speed of the simulated low-pressure rotor of turboprop engine was lower than the bending critical speed.This rotor can not reach the working speed due to vibration exceeding the limit,which was caused by unbalance.Aiming at the problem above,the dynamic balance test research was studied in this paper.First of all,low speed balance of the simulated low-pressure rotor was carried out on the dynamic balance machine,and then combined with high-speed dynamic balance technology of flexible rotors,the high-speed dynamic balance test was completed on the high-speed rotating test rig.Vibration is obviously reduced after the dynamic balance test,the vibration characteristics of the rotor after dynamic balance is good.Balancing effect is ideal.The research will provide effective method for vibration control of aero-engine rotors of same type at high speed,which is of great application value.
