摘要

本文论述了采用无线电遥测技术，在电站运行的机组上实测低压末级７１０ｍｍ叶片动频率及动应力，并对其进行分析。该级叶片振动特性的实测数据对机组安全运行具有指导意义。

Abstract

Abstract Described in this paper is on-site measurement of the dynamic frequency and stress of 710 mm long last stage blades by using a redio telemetric device on the operating turbine

and the results were analysed as well.The vibration behaviours of the measured blades are of significance for reliable operation of turbine units.
