英文摘要: |
Rotor unbalance is the main excitation source of aeroengine,which directly affects the reliability of engine and the service
life of components. In order to reduce engine vibration,the SAE ARP4163 standard evaluation method was adopted for CFM56 engine highpressure
compressor rotor,and the technical difficulties such as setting the initial unbalanced quantity and balancing the multi-correction
planes were deeply studied. The results show that the precision design of the initial unbalance quantity (≤3048 g.mm)and the residual
unbalance quantity(G3.6 balance grade)of the CFM56 engine high-pressure compressor rotor is reasonable,and the multi-planes balance
process method is effective based on the initial unbalance quantity control. The rotor positioning reference error is applied to identify
important parts and the influence coefficient of the counterweight on each correction surface is calculated and analyzed ,which can achieve
the optimal balance results efficiently. |
