摘要
本文介绍了一种用纯机械参数质量——弹簧——阻尼所组成的二阶系统动态性能测量的实验台.文中对该实验台的结构特点、原理及参数的确定分别做了介绍,并以该系统的阶跃时间响应实验为主线,通过数理分析,证明了实验结果与理论分析是基本一致的.
The paper introdues a mechanical experimental platform,whch is composed of pure mechanical parameters:mass,spring and damping,in determining second order system dynamic behaviour.It analyzes synthetically the platform structure,principle and the determining of parameters and takes the system experiment of step respons as main line and through mathematical analysis to prove that the experimental results are in basic agreement with theoretical analyses.
