基于实验台的动态特性测定实验研究

Study on the determination of the dynamic dharacteristics of the system based on the experimental

基于传感器与测控技术实验台研究了用于高校教学的动态特性测定实验。该研究利用了现有的实验设备,将二阶系统振动源作为测试对象,运用了线性系统简谐信号输入和输出的特性,应用了示波器两个通道同时得到的李萨茹波形,完成了振动源的幅频特性和相频特性测定。

This article has studied the dynamic characteristics experiment based on the experimental for teaching in colleges and universities. The study has made use of existing experimental equipment and the two order system vibration source as the test object. It is used for input and output characteris- tics of the linear systems and Li Saru waveform of oscilloscope in two channels. It has completed spe- cific of amplitude frequency characteristic and the phase frequency characteristic for the source of vi- bration
