摘要
针对已往确定汽轮发电机组轴系扭振固有频率时需要对轴系施加大的扭振激励，易对轴系造成损伤，提出一种新方法，用此方法研制的仪器解决了上述问题，并在现场应用中取得了圆满的效果。此仪器采用数字电路实现，具有抗干扰能力强、精度高、操作简便等特点。
Formerly, in order to get torsional eigenfrequency of steam turbine-generator shaft, it was a requirement of high excitation on the shaft. As so, the shaft damage was easily occured. This paper presents a new method to design the detecting instrument with the better characteristics. It's application to the detection of unit in site meets the requirement of lower excitation and higher precision.
