摘要
对影响脉冲涡流传感器空间磁场的参数进行研究。建立了一种传统脉冲涡流传感器模型,根据理论和仿真计算结果及电磁场矢量原理对传感器结构进行优化,结果表明:优化后的传感器其磁场强度提高了71%,磁场聚焦范围缩小了58%,且磁场梯度较大。搭建试验台采用磁电阻效应传感器对空间磁场进行测量,进一步验证传感器结构优化的可靠性,对影响传感器性能指标的参数进行分析,得出各参数对传感器性能影响的数学模型和变化规律,为脉冲涡流传感器的设计提供了有价值的参考。
It analyzes the parameters that affect the spatial magnetic field of pulsed eddy current sensors,establishes a traditional pulse eddy current sensor model,and optimizes the sensor structure based on theoretical and simulation calculations,as well as the principle of electromagnetic field vector.The results show that the optimized sensor has a 71%increase in magnetic field intensity,a 58%reduction in magnetic field focusing range,and a large magnetic field gradient.Building a test bench using magnetoresistance effect sensors to measure the spatial magnetic field,it verifies the reliability of sensor structure optimization,analyzes the parameters that affect sensor performance indicators,and obtains mathematical models and variation patterns of each parameter's impact on sensor performance,provides valuable reference for the design of pulse eddy current sensors.
