摘要
针对航空发动机风扇/增压级转子平衡工艺规划过程中平衡转速设定的问题,通过考虑叶片榫槽间隙、平衡设备性能和转子气动扭矩等因素,构建风扇/增压级转子平衡转速计算模型。将某型发动机风扇/增压级转子的结构及性能参数带入模型,计算得到转子的平衡转速,并与国外相似型号转子的平衡转速进行了比较。结果表明:通过模型计算得到的转子平衡转速为685 r/min,与国外相似型号转子的平衡转速基本一致,并且满足该型风扇/增压级转子的实际平衡需求。该平衡转速计算模型已经成功应用到风扇/增压级转子平衡的设计和工艺文件中,提升了风扇/增压级转子平衡工艺的正向设计能力。
Aiming at the problem of setting balance rotational speed in the balance process planning of aeroengine fan/booster rotor,by considering the factors such as clearance of blade dovetail,the performance of balancing machine and the rotor aerodynamic torque,the calculation model of balance rotational speed of fan/booster rotor was constructed. The parameters of structure and performance of an engine fan/booster rotor were brought into the model,and the rotor balance rotational speed was calculated and compared with that of similar foreign rotors balance rotational speed. The results show that the rotor balance rotational speed calculated by the model is 685 r/min,which is basically consistent with that of similar foreign rotors balance rotational speed,and meets the actual balance requirements of this type of fan/booster rotor. The balance rotational speed calculation model has been successfully applied to the design and process documents of fan/booster rotor balance,which improves the design ability of fan/booster rotor balance process.
