摘要：In order to investigate the lack of characteristic parameters and verification method of the electrostatic sensor for on-line debris monitoring in aero-engine lubricated system, the corresponding characteristic parameters were proposed according to the basic principle of electrostatic induction and the structure of sensor. Sensing model of ring probe was used for simulation, and the rig of electrostatic sensor experiment system was designed and built. Dynamic characteristics of the oil-line electrostatic sensor were analyzed and validated by experiments. Results showed that the proposed parameters can effectively reflect the dynamic characteristics of the electrostatic sensor. The ratio of length to diameter was an important structural parameter of the ring oil-line electrostatic sensor, and the sensor efficiency increased with the increasing ratio of length to diameter. The effective field of view of the sensor also increased with the increasing size of the probe. Furthermore, the experiment rig can be applied to the analysis and experiment of the dynamic characteristic of the actual sensor with good repeatability. The simulation and experimental results have important guiding significance for the design and application of the oil-line electrostatic sensor. © 2017, Editorial Department of Journal of Aerospace Power.
