摘要
针对电感式磨粒传感器易受磨粒连续性影响和无法识别磨粒材质的问题,通过增大电感式磨粒传感器中磨粒的涡流作用,提出一种电涡流磨粒传感器。结合有限元软件ANSYS Maxwell建立电涡流磨粒传感器的仿真模型,并对不同材质和尺寸的磨粒进行仿真分析,验证电涡流原理在磨粒监测中的可行性。对不同激励频率及线圈内径的电涡流磨粒传感器进行仿真分析。仿真结果表明:电涡流作用可以识别磨粒尺寸,磨粒产生的涡流作用与磨粒尺寸成三次方关系;电涡流作用可以识别磨粒材质,不同材质的磨粒在相同的磁场环境中产生的涡流作用不同;线圈的激励频率越高,磨粒的涡流作用越大;线圈的内径越大,磨粒的涡流作用越小。
Aimed at the problems that inductive wear debris sensor is easily affected by the continuity debris and cannot identify the material of debris,an eddy current wear debris sensor was proposed by increasing the eddy current effect of debris in inductive wear debris sensor.Combined with ANSYS Maxwell,the simulation model was established,and the debris of different material and size was simulated,which proved the feasibility of eddy current principle in debris monitoring.The excitation frequency and the inner diameter of the coil were simulated.The simulation results show that the eddy current effect can identify the size of debris,and the eddy current effect is in a cubic relationship with the size of the debris.The eddy current effect can identify the material of debris,and different material of debris have different eddy current effects in the same magnetic field environment.The higher the excitation frequency of the coil,the greater the eddy current of the debris.The larger the inner diameter of the coil,the smaller the eddy current of debris.
