摘要

阐述了差动变压器式电感位移传感器的工作原理

提出了目前常用电感传感器铁芯在机械安装方面存在的问题

并根据磁轴承系统的特点

在传统铁芯结构的基础上加以改进

设计了"一体化"结构的位移传感器

并利用ANSYS与MATLAB进行分析。结果表明:"一体化"结构的传感器不仅便于加工与安装、避免铁芯的不对称

而且性能不亚于原结构传感器

完全适用于磁悬浮轴承系统。

Abstract

The working principle of differential transformer inductive displacement sensor is described

the problems in machinery installation of iron core of common inductor sensor are put forward

and according to the characteristics of the magnetic bearing system

it is improved on the basis of the traditional structure. The displacement sensor with"integrated"structure is designed

and analyzed by ANSYS and MATLAB. The results show that the improved scheme is not only convenient for processing

installation and avoids the asymmetry of the iron core

but also the performance of the sensor is no less than the original structure of the sensor

fully suitable for magnetic levitation bearing system.
