STUDY ON LAST STAGES BLADES VIBRATION BEHAVIOURS OF A 200MW TURBINE UNIT WITH DRY COOLING[J]. Thermal power generation, 1998, (1). DOI: 10.19666/j.rlfd.1998.01.006.
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.
