摘要
为了实现油液金属磨粒的高精度测量,基于微流体制备了一种可检测电阻电感参数的磨粒传感器。通过仿真获得了金属颗粒在时谐磁场中的磁化和涡流效应特征,并通过实验研究了电阻电感检测的电压特性和频率特性。高频激励可以增强金属颗粒内部的涡流效应,而激励电压对传感器检测结果的影响不大。研究表明电感参数对铁磁性金属的检测能力强,电阻参数对非铁磁性金属的检测能力强。采用2.0 V、2.0 MHz的激励,通过比较分析电阻和电感检测结果,该传感器可有效识别直径60μm的铜颗粒和直径16μm的铁颗粒。这种基于线圈电阻参数检测非铁磁性金属磨粒的方法为增强磨粒传感器的综合测量性能提供了新思路。
A microfluidic-based sensor which might detect resistance and inductance parameters was fabricated to achieve high-precision measurement of metal debris in oil.The characteristics of magnetization and eddy current effects of metal particles in harmonic magnetic field were obtained by simulation,and the voltage and frequency characteristics of resistance and inductance detections were also studied by experiments.High-frequency excitation might enhance the eddy current effects inside metal particles,and excitation voltages had little effects on the detection results of sensors.The results show that inductance parameter has stronger detection ability for ferromagnetic metals,and resistance parameter has stronger detection ability for non-ferromagnetic metals.At 2.0 V,2.0 MHz excitation,the sensor may effectively identify 60μm diameter copper particles and 16μm diameter iron particles by comparing and analyzing resistance and inductance detection results.The method of detecting non-ferromagnetic metal debris based on coil resistance parameters provides a new way to enhance the comprehensive performance of debris sensors.
