| 摘 要： | 为了提高在线式磨粒监测传感器的监测灵敏度，设计了一种内置纳米晶体磁环的电磁式磨粒传感器.通过建立传感器内部磁场分布及输出感应电动势的数值模型，系统地研究了传感器感应线圈磁环和激励线圈磁环尺寸特征对磨粒监测灵敏度的影响规律.仿真及实验结果表明:纳米晶体磁环对传感器灵敏度具有显著影响.具体表现为:为激励线圈和感应线圈同时添加特定尺寸的磁环可使磨损颗粒引起的传感器输出感应电动势幅值增大4~7倍.该方法可大幅提高传感器对微小磨粒的监测能力，对大型机械设备的早期故障诊断和故障预警具有重要意义.

| Abstract: | In order to improve the sensitivity of the on-line wear particle monitoring sensor,an electromagnetic wear particle sensor with a built-in nanocrystalline magnetic ring was proposed.By establishing a numerical model of the sensor's internal magnetic field distribution and output induced electromotive force,the influence of size properties of the induction coil ring and the excitation coil rings on the sensitivity of wear particle monitoring sensor was systematically analyzed.The simulation and experimental results show that the nanocrystalline magnetic ring has a significant influence on the sensor sensitivity.Moreover,adding magnetic rings to both the excitation coil and the induction coil can dramatically increase the amplitude of electromotive force induced by wear particles to 4~7 times.Therefore,the monitoring ability of the designed sensor can improve effectively,especially for the small wear particles of 50 μm to 100 μm.The study is of great significance for the early fault diagnosis and fault warning of large mechanical equipment. |
