Abstract

In order to investigate the method to improve the sensitivity of oil wear particle sensor with large oil flow, a modified model of three-coil wear particle sensor was established. Nanocrystalline material rings with high permeability was added into the coil of sensor. Based on Maxwell's equations, the physical model of magnetic field in the sensor-particle system was simulated by finite element method. The effect of nanocrystalline material ring on the amplitude of induction electromotive force signal in induction coil and excitation coil is analyzed emphatically. Simulation shows that nanocrystalline material can increase the amplitude of induced electromotive force signal by 2-10 times, therefore the ability of sensors to detect small wear particles of 50-100μm is greatly enhanced.
