Abstract
In a method for influencing, in particular damping or suppressing, mechanical vibrations occurring during operation in a turbomachine blade (), the mechanical vibratory energy of the turbomachine blade () is first converted into electrical energy and the electrical energy generated is then converted into heat loss. Effective damping which can be used especially simply and in a versatile way is achieved in that the piezoelectric effect is used in order to convert mechanical vibratory energy into electrical energy.
