Improved Blade Tip Timing in Blade Vibration Monitoring with Torsional Vibration of the Rotor
Journal of Physics: Conference Series, 2012 Due to the complex conditions in rotating machinery, the blades usually encounter fluctuating loads, and failures may occur in the operation. Blade vibration is rarely monitored in the practical rotating machinery in power plants as the traditional blade vibration method using strain gauge method is hard to be applied in long-time and online monitoring.

On The Vibration of a Cracked Rotating Blade [PDF]
Shock and Vibration, 1998 The dynamic behavior of a rotating blade containing a transverse crack was investigated. First, the local flexibility of the cracked blade was obtained by using the method of the released energy. An energy principle, in conjunction with a weighted residual method, was then applied to yield the discrete equations of motion.

Vibrations of a Rotating Blade
The Journal of the Japan Society of Aeronautical Engineering, 1956 The bending vibrations of a rotating blade were investigated by some authors. But, as in the aerofoil seetion the centre of gravity and the centre of twist do not coincide the coupling of bending and twisting vibrations occurs necessarily.In the present investigation the frequencies of the above mentioned coupled vibrations of a rotating blade which ...

Resonance and Instability of Blade-Shaft Coupled Bending Vibrations with In-plane Blade Vibration
International Journal of Fluid Machinery and Systems, 2008 Abstract As a major component of a power plant, a turbine generator must have sufficient reliability. Longer blades have lower natural frequency, thereby requiring that the design of the shaft and blade takes into account the coupling of the blade vibration mode, nodal diameter k =0 and k =1 with vibration of the shaft.
