中文摘要:

磁场均匀性是影响电感式磨粒传感器检测精度的重要因素,为了提高传感器磁场均匀性，研究线圈参数对传感器磁场分布规律，根据磁场叠加原理，建立了电感式磨粒传感器三线圈数学模型，推导出传感器磁场计算公式，提出磁场均匀性评价系数K。对电感式磨粒传感器磁场进行仿真，分析了线圈内径、线圈宽度、线圈间距以及线圈匝数对传感器磁场分布的影响。通过极差分析和方差分析分别得到磁场均匀性最优线圈参数组合和线圈参数对磁场均匀性影响的显著性。实验结果表明：当线圈为最优参数时，传感器对70～200 μm的磨粒有良好的监测能力，磨粒在不同径向的监测结果偏差小于5%，为传感器线圈的设计提供了参考。

英文摘要:

The uniformity of magnetic field is an important factor affecting the detection accuracy of inductive abrasive sensor. In order to improve the uniformity of the magnetic field of the sensor and study the distribution of coil parameters on the magnetic field of the sensor, the mathematical model of the three coil of the inductive abrasive particle sensor is established according to the principle of magnetic field superposition. The calculation formula of the magnetic field of the sensor is derived and the evaluation coefficient K of the magnetic field uniformity is proposed. The magnetic field of the inductive abrasive particle sensor was simulated, and the influence of the inner diameter of the coil, the width of the coil, the spacing of the coil and the number of turns of the coil on the magnetic field distribution of the sensor was analyzed. Through the range analysis and analysis of variance, the significance of the optimal combination of coil parameters and the influence of coil parameters on the uniformity of the magnetic field are obtained. The experimental results show that when the coil is the optimal parameter, the sensor has good monitoring ability for the abrasive grains in the range of 70 to 200 μm. The deviation of the abrasive particles in different radial monitoring results is less than 5%, which provides a reference for the design of the sensor coil.
