摘　　要：航空发动机风扇叶轮动平衡差会引起发动机内部轴承及叶片等零部件的损坏,导致发动机振动,整体性能下降。针对某航空发动机风扇叶轮的动平衡定点定量去除加工要求,提出了一种多传感器融合的自动化加工方法。该方法基于六自由度机器人系统及数控转台,将测量传感器与力学传感器相融合,利用机器人控制技术来实现风扇叶轮的自动化磨抛,并进行理论去除量与实际去除量的对比实验分析。实验结果表明,当磨抛区间>10°时,理论去除量和实际去除量的差值在±1%以内,验证了所提出的预测磨抛区间的准确性与加工方法的可行性。与传统的人工磨抛或复杂昂贵的机床磨抛加工相比,此方法对于航空发动机风扇叶轮定点定量去除具有集成度高、效率高、普及性强等优点,为航空发动机的制造提供有力的技术支撑。The dynamic balance difference of aero-engine fan impeller will cause the damage of internal engine bearings and blades,resulting in engine vibration and overall performance decline.In this paper,an automatic machining method based on multi-sensor fusion is proposed for the quantitative removal of an aero-engine fan impeller based on dynamic balance.The method is based on a six-degree-of-freedom robot system and a CNC turntable.By integrating the measurement sensor and the mechanical sensor,the robot control technology is used to realize the automatic grinding and polishing of the fan impeller,and the theoretical removal amount is compared with the actual removal amount.The experimental results show that the difference between the theoretical and actual removal amounts is within±1%when the grinding and polishing interval is greater than 10°,which verifies the accuracy and feasibility of the proposed machining method.Compared with traditional manual polishing or complex and expensive machine grinding,this method has the advantages of high integration,high efficiency and strong popularity for the fixed point quantitative removal of aero-engine fan impeller,which provides a strong technical support for the manufacture of aero-engine.
