METHOD FOR AFFECTING MECHANICAL VIBRATION OCCURRING DURING OPERATION IN TURBO MACHINE BLADE, TURBO MACHINE BLADE FOR EXECUTING THE METHOD, AND PIEZOELECTRIC DAMPING MEMBER TO BE ASSEMBLED TO THE TURBO MACHINE BLADE

摘要

PROBLEM TO BE SOLVED: To provide a method that is simple and superior in point of extremely wide enablement.SOLUTION: Mechanical vibration energy of a turbo machine blade 10 is first converted into electric energy. Subsequently, the generated electric energy is converted into heat loss. In a method for affecting mechanical vibration occurring during operation in the turbo machine blade, a piezoelectric effect is used for converting the mechanical vibration energy to the electric energy.
