基于LabVIEW的非线性电磁力混沌实验仪的虚拟仪器设计
|
摘要
文章依据非线性动力学混沌理论,设计了非线性电磁力振动装置,并以此为基础,利用LabVIEW开发平台进行了虚拟仪器(virtual instrumentation,VI)设计。该虚拟仪器系统能对振动信号自动采集、实时处理、生成振动波形图和相图,可以直观观察混沌现象并可做定量研究。此外,系统还增加了理论计算模块,实验测量可与理论计算的波形图像进行对比。
According to the chaos theory of nonlinear dynamics, the nonlinear electromagnetic vibration device is designed. On this basis, the virtual instrumentation(VI) for the observation and quantitative study of chaos is developed using LabVIEW development platform. The system can automatically acquire vibration signals, process them in real time and generate vibration waveforms and phases diagrams. In addition, the theoretical calculation module is developed, and the waveforms obtained by the experimental measurement can be compared with those by the theoretical calculation.
