摘要
简要介绍了由虚拟仪器构建的二自由度动力减振系统,在建立的系统模型基础上,构建信号源,设计硬件电路,保证在同一界面上系统在分析振动信号的同时输出一电平幅值可调的直流信号,控制实验平台的激振频率。实验表明,实现了对振动信号实时调节、控制以及信号处理的目的,达到合理的减振效果。
This paper introduces the dynamic damping system with two freedoms based on virtual instrument. On the basis of system model, the signal generator is built, and hardware circuit is designed. At the same time, the system is analyzing the vibration signal, and the variable scope direct current signal is output to control the exciting frequency for the experimental platform. It is achievable for real-time regulating, controlling and processing the vibration signal by experiments, so that the reasonable damping effect is realized.
