Method for influencing mechanical vibrations generated during operation in a turbomachine blade, turbomachine blade for carrying out the method, and piezoelectric damping member for assembly on the turbomachine blade

摘要

The method involves converting mechanical vibratory energy of the turbomachine blade (10) into electrical energy. The electrical energy is piezoelectrically converted into heat loss. The piezoelectric damping elements (SPE1,SPE2) are attached in the turbomachine blade. The damping elements are provided with a capacitor that includes a piezo structure which is arranged between the electrodes. Independent claims are included for the following: (1) turbomachine blade; and (2) piezoelectric damping element.
