摘要

本文介绍了一种全自动环芯磁滞量测量系统。该系统基于美国国家仪器公司的PXI-4461双通道动态信号生成和双通道采集卡。设计并制作了基于TDA2030单片机的功率放大器，并在LabVIEW中编写了控制测量过程的计算机代码。系统采用模拟RC集成。该系统允许用图形表示测量到的磁滞曲线，并计算和表示第一磁化曲线，近似于对称磁滞周期的轨迹点。第一磁化曲线可以在有限元分析(FEA)软件中导出为导入准备的格式。

Automated system for the measurement of AC magnetization characteristics

The paper presents a fully-automated system for the magnetic scalar hysteresis measurement of the ring core specimens. The system is based on the National Instruments PXI-4461 two-channel dynamic signal generation and two-channel acquisition cards. A power amplifier is designed and manufactured, based on the TDA2030 monolithic integrated circuit, and a computer code for controlling the measurement process is programmed in LabVIEW. The system applies the analog RC integration. The system allows graphical presentation of the measured hysteresis curves, and calculation and presentation of the first magnetization curve, approximated by locus points of the symmetric hysteresis cycles. The first magnetization curve can be exported in a format prepared for the importing in the finite element analysis (FEA) software.
