Application of Piezofilms for Excitation and Active Damping of Blade Flexural Vibration

Application of Piezofilms for Excitation and Active Damping of Blade Flexural Vibration

The steam turbine blades of low pressure stages are endangerd by the high-cyclic fatigue due to the combined loading of dynamic stresses by the steam time-variant pressure and the pre-stress from centrifugal forces. Therefore, the importance of their experimental dynamic analysis in the design stage...
