平面线圈油液磨粒传感器仿真研究

Study on the Simulation of Planar Coil Oil Grinding Sensor

摘要: 机械设备发生故障，大多数是由机械设备中磨损颗粒引起的。油液中的磨损颗粒可以直接反应出机械设备的状态。油液磨粒在线监测技术可以有效的检测油液中磨粒的浓度与大小，从而确定机械设备运行的状态。磨损颗粒穿过油液磨粒检测传感器时，会使传感器产生的磁场发生变化。本文应用ANSYS Maxwell软件建立了一个平面线圈油液磨粒检测传感器模型，并对其进行了瞬态和稳态两方面有限元仿真分析，得到了稳态时传感器不同参数对检测效果的影响以及瞬态时磨粒穿过平面线圈传感器的磁场变化规律。研究结果对于平面线圈油液磨粒检测传感器参数优化具有重要的意义。

Abstract: Mechanical failures are mostly caused by the wear particles in the equipment. Detection of wear particles in the oil can effectively reflect the state of mechanical equipment. Online oil debris monitoring technique can effectively detect the concentration and the size of abrasive particle in the oil, thereby it can successfully monitor condition of mechanical equipment. When a particle passed through the sensor, the magnetic field of the sensor will be changed. An oil debris sensor with planar coil model has been established using ANSYS Maxwell software in this work. Two as-pects of the transient and steady states of the model have been analyzed. Research on the influ-ences of different parameters on the sensor in the steady state and the variation of abrasive passing through the sensor have been thoroughly conducted. The results of simulation have important meanings for the parameter optimization of oil debris sensor with planar coil.
