摘要
为研究铁精粉加工或贸易过程中铁品位的实时快速测试问题,给出了铁精粉铁品位测量原理和自感式铁品位传感器的设计方法,利用ANSYS12.0有限元仿真软件建立圆柱型铁精粉铁品位传感器的3-D电磁场仿真模型,对电感传感器谐波磁场进行了仿真分析,明确了传感器自感系数(线圈内径、线圈外径、漆包线匝数、线圈高度)分别变化时输出电感的相应变化规律.在此基础上,进一步建立正棱柱型铁品位电感传感器的3-D电磁仿真模型,得出正棱柱形铁品位传感器自感系数改变对输出电感的影响规律,与圆柱型传感器进行对比,确定铁精粉铁品位传感器最优结构型式和最佳结构参数组合,为进一步实现传感器性能优化奠定必要基础.
Measuring principle for detecting iron grade of fine iron powder is introduced, and designing method for self-inductance iron grad,, inductance sensor is given. ANSYS12.0 Smart Engineering Simulation was employed to build 3D electromagnetic field simulation model of cylinder fine iron powder grade sensor. Simulation and analy- sis of inductance sensors harmonic magnetic field was accomplished by using this simulation model. Therefore, the corresponding variation law of output inductor varied with every sensor self-inductance coefficients （ coil diameter, coil diameter, enameled wire circle number, coil height） was explored. Furthermore, 3D electromagnetic simulation model of prism-shaped iron grade inductance sensor was built. Then, the variation law of output inductor corre-sponding to the variation of prism-shaped iron grade sensor self-inductance was obtained, which was contrasted with cylinder one. So the optimal structure and best structure parameter combination of fine iron powder grade sensor was defined, which lay a foundation for the further achievement of sensor performance optimization.
