基于LabVIEW的机械系统频率特性谐波扫描法测试实验系统

Experiment system for testing frequency property about mechanical system using harmonization sweep based on LabVIEW

为了改善控制工程基础实验课以验证性实验为主之现状，设计开发了以LabVIEW为平台的机械系统频率特性测试的谐波扫描法实验系统。实验内容包括方案设计、传感器应用、信号采集与分析以及控制理论知识。该实验丰富了机械类控制工程基础实验内容，巩固了学生的基础理论知识。教学实践证明效果显著。

In order to improve present status that proving experiments occupied on master position during control engineering basic course teaching, the experiment for frequency property of mechanical system using harmonization sweep method was designed and realized based on LabVIEW. Through this experiment, scheme de- sign, sensor application, signal collection and analysis, and control theory knowledge were presented. So experiment content was enriched for the course of control engineering basic, and basic theory of students was secured. Teaching experience proved that the teaching effect was very significant.
