摘 要:航空发动机转子不平衡是引起发动机试车振动故障的主要因素之一,在发动机生产和修理过程中,研究转子动平衡校正技术来降低发动机振动是十分有必要的。探索3种动平衡校正方法来降低某型发动机转子不平衡量,研究结果表明:当转子剩余不平衡量较大时,应选择双面同时校正,在一定程度上可使转子的不平衡量迅速降低;当转子剩余不平衡量较小且对平衡精度要求较高时,双面校正很难保证理论与实际一致,会造成2个校正面相互影响,转子重心容易偏移,平衡校正次数增加,应选择单面分别校正,可使转子更稳定、更快速达到平衡要求。Aviation engine rotors imbalance was one of the main factors that caused the engine test vibration failure,and during engine production and repair,it was necessary to study rotors balance correction techniques to reduce engine vibration.Three dynamic balance correction methods were explored to reduce the unbalance of rotors of the engine.The results showed that when the remaining amount of the rotor was large,the double-sided simultaneous correction should be selected,the amount of imbalance of the rotor could be lowered rapidly to a certain extent.When the remaining amount of the rotor was small and the requirement of balance accuracy was high,it was difficult to ensure that the theory and practice of double-sided correction were consistent,which resulted in the mutual influence of the two calibration front,the center of gravity of the rotor was easy to shift,the number of balance correction increased,so it was necessary to choose single side correction,which could make the rotor more stable and faster to achieve balance requirements.
