| Abstract: | View on Security analysis of the penultimate stage "474" & "475" blades of the imported 300MW and 600MW steam turbine is made clear, which shows that the difference of the second mode of frequency vibration between the two kinds of blades is the key to the invalidity of "474" blade and safe operation of "475" blade. |
