摘要： 磨损区域静电传感器常用于航空器关键部件磨损的在线监测。为了对该新型传感器的监测性能进行研究，建立了棒状磨损区域静电传感器的数学模型及其性能测试平台，对传感器的空间灵敏度、工作效率、有效视场等特性参数进行了仿真计算和测试。结果表明：空间灵敏度随着探极感应面半径的增大而增大；工作效率随着径距比的增大而增大；工作效率的仿真值与测试值的变化趋势一致，证明了所建磨损区域静电传感器数学模型的正确性；有效视场随着探极感应面半径的增大而增大。研究结果对新型磨损区域静电传感器的设计优化及其应用具有重要的指导意义。
Abstract: The wear-site electrostatic sensor is often used for on-line monitoring of wear of key components of aircraft. In order to study the monitoring performance of the new sensor, a mathematical model and a performance testing platform for the rod-like wear-site electrostatic sensor were established, and the spatial sensitivity, working efficiency, effective field of the sensor were simulated and tested. The results showed that the spatial sensitivity increased with the increase of the radiuses of probe sensing surface. The working efficiency increased with the increase of ratio of radius to distance. The variation trend of the simulation value of working efficiency was consistent with that of the test value, which proved the correctness of the mathematical model of wear-site electrostatic sensor. The effective field of view increased with the increase of the radius of probe sensing surface. The research results have important guiding significance for the design optimization and application of the new wear-site electrostatic sensor.
