摘要
对常用的数字测速方法进行了分析 ,说明由于转轴弯曲振动及扭振的影响 ,在实际应用时应根据不同的转速范围选用不同的方法 。
The commonly used measuring methods for turbine speed are analyzed. It is stated that in order to meet static accuracy and faster dynamic response, in practical situation different method shall be selected for different range of the speed because of the influence of the vibration caused by crooked or twisted shaft.
