LabVIEW在测量装置动态特性分析中的应用

Application of LabVIEW in Dynamic Characteristic Analysis of Measurement Equipment

针对传统测量装置动态特性参数分析方法的不足,运用图形化编程语言LabVIEW设计了特性参数分析软件。利用LabVIEW强大的信号处理和数学运算功能实现了动态特性参数(固有频率、阻尼比等)的实时计算和分析。实验结果表明,软件具有良好的人机界面,易于操作,计算结果准确,效率较高,可以满足工业测试的需要。

In view of the disadvantages of traditional analytical method on dynamic characteristic parameter of measurement equipment, the analytical software of characteristic parameter was designed based on the graphical programming language LabVIEW. Dynamic parameters （inherence frequency, damp, etc. ） were carried out in real time by powerful capability of LabVIEW in signal processing and mathematical computation. The experimental results manifested that it had friendly user-interface and could be operated easily. Also the result is correct and the efficiency is high. So it can be competent for industrial measurement.
