柔性涡流阵列传感器的磁场计算分析

摘要

A flexible eddy current array sensor consists of six array units( spiral coil)is designed,establish electromagnetic field model for flexible eddy current array units based on electromagnetic field theory,the magnetic field strength formula in radial and axial of flexible array unit coil are derived,simulation analysis on relationship between array unit coil magnetic field strength and current,coil gap,inner and outer diameters and other parameters,which have a certain reference value for development of flexible eddy current array sensor.%设计了一种由6个阵列单元（螺旋线圈）所组成的柔性涡流阵列传感器，基于电磁场理论建立柔性涡流阵列单元的电磁场模型，推导出柔性阵列单元线圈径向和轴向的磁场强度计算公式，仿真分析阵列单元线圈磁场强度与电流、线圈间隙、内外径等参数的关系，对柔性涡流阵列传感器的发展具有一定参考价值。
