- In this study the authors measured 4 blades vibration stress by 4ch FM telemeter for estimating the disk vibration and vibration stress is calculated by unsteady CFD with interaction between nozzle vanes and blades. The authors found 4 blades stress were different and agreed with disk vibration mode calculated by numerical simulation. The 4 blades simultaneous measurement technique is confirmed useful in case of changing disk vibration mode. The blade vibration stress obtained by the numerical analysis shows good agreement with measurement.
