摘　　要：为了改善控制工程基础课程以验证性实验为主的现状，设计开发了以LabVIEW为平台的机械系统频率特性测试的脉冲法实验，实验内容包括方案设计、传感器应用、信号的采集与分析等。介绍了脉冲法原理、方案设计及系统的组成，给出了实验结果。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 are at main position during control engineering basic course teaching, the experiment, for testing frequency property of mechanical system by using impulse method, was designed and realized based on LabVIEW. Through this experiment, scheme design, sensor application, signal collection and analysis, and control theory knowledge were presented. So experiment content was enriched for the course of control engineering foundation, and the knowledge of basic theory of students was solidified. The teaching experience proved that the teaching effectiveness was very significant.
