摘　　要：对民用飞机发动机状态监测和故障诊断方法进行了研究,提出了一种能够实时反映零件故障信息的油液在线静电监测方法,设计并搭建了一套静电监测系统及实验平台,开展了循环润滑条件下销盘滑动摩擦磨损实验,使用自制的油液静电传感器对油路中磨粒进行监测。实验结果表明油液静电传感器能够监测到金属材料荷电颗粒,感应电压幅值与磨粒大小具有相关性,感应电压波形与磨粒荷电特性有关,验证了静电传感器在线监测的有效性,为判断故障提供了进一步的依据。The method of civil aircraft engine condition monitoring and fault diagnosis is studied. Come up with a new monitoring techniques, which can reflect real parts fault information, early warning failure. In this paper, e- lectrostatic monitoring principle is analyzed, and electrostatic monitoring system and experimental platform had been designed and developed. The eireulation lubrication conditions pin plate sliding friction and wear experiment is car- ried out, using a homemade electrostatic sensor circuit in fluid abrasive grains to montor. The results show that the oil-line electrostatic sensor can monitor the charged particles of various metallic materials, inductive voltage is rele- vant to the debris size, shape of the inductive voltage is relevant to the debris charging characteristics, indicating availability of on-line monitoring in the model of electrostatic sensor and providing a further evidence for the fault.
