摘要
利用变频器、同步电动机和磁性书写板来改进受迫振动与共振演示实验装置.本装置可以用来定量演示受迫振动,还可以用来研究共振的发生条件及描绘共振曲线.
This paper introduces a method that uses frequency transformer, synchronous motor and magnetic writing board to improve the experiment device of forced vibration and resonance. The improved device can be used not only to demonstrate forced vibration, but also to study resonance condition and plot resonance curves.
