摘要: 当机械系统工作时,由于各机械单元相互作用,其内部会产生不同程度的磨损,生成的磨粒会随油液四处流动,若不及时检测则会加剧磨损进程,影响整个机械系统的使用寿命。油液中的金属磨粒蕴含着丰富的摩擦学信息,其材质和粒径对判断机械设备运行状态具有重要的参考价值。为了实现油液中金属磨粒的区分检测,设计一种兼具通量和检测精度的三线圈传感器,该传感器的激励信号和数据采集均采用集成的数字锁相板卡,具有较高的集成度。分别从外形封装、磁场仿真和试验验证三个方面进行传感器设计和性能测试,仿真得到的颗粒曲线与试验结果一致。对不同粒径的铁颗粒和铜颗粒进行了测试,并通过理论计算得到该传感器可以实现最小23 μm的铁颗粒和50 μm的铜颗粒检测。这种三线圈传感器为便携式磨粒检测设备的开发提供了新思路。

Abstract: When the mechanical system works, due to the interaction of the mechanical unit, its internal will produce different degrees of wear, the generation of abrasive particles will flow around with the oil, if not detected in a timely manner will exacerbate the wear process, affecting the service life of the entire mechanical system. The metal abrasive particles in the oil contain rich tribological information, and their material and particle size are important reference values for judging the operation status of mechanical equipment. To achieve the differentiated detection of metal abrasive particles in oil, this designs a triple-coil sensor with both flux and detection accuracy, which adopts an integrated digital phase-locked board for the excitation signal and data acquisition with a high integration degree. The sensor design and performance testing are carried out from three aspects, namely, form factor packaging, magnetic field simulation, and experimental verification, respectively, and the particle profiles obtained from the simulation are consistent with the experimental results. Iron and copper particles with different particle sizes were tested, and theoretical calculations showed that the sensor can achieve the detection of iron particles with a minimum size of 23 μm and copper particles with a minimum size of 50 μm. This triple-coil sensor provides a new idea for the development of portable abrasive particle detection equipment.

Key words: triple-coil sensor, oil detection, inductance detection, wear particle detection, phase-locked amplification
