基于Labview的磁滞回线测量

Measurement of hysteresis loop based on Labview

利用Labview的图形化开发平台和数据分析处理功能代替了原先的硬件积分过程并实现了磁滞回线的自动测绘。在此基础上,针对实验室教学需要,本文设计完成了磁滞回线测量的虚拟实验的主要构成部分,虚拟实验的开发将对实验教学提供很大的帮助和支持。

Electronic integrator and filters are used to measure hysteresis loop, but these methods need hardware supports. In this paper, Labview is used to submit electronic integrator. Data acquisition and data analyzing are carried out by Labview system, and the measurement result of hysteresis loop is displayed and stored automatically. In addition, we design the main virtual experiments program of hysteresis loop, which will be helpful and beneficial to experiments teaching.
