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.
