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.

Method for influencing, damping, or suppressing mechanical vibrations occurring during operation in a turbomachine blade, a turbomachine blade useful for carrying out the method, and a piezoelectric damping element

An ultrasonic transducer having an ultrasonic conducting element with a plurality of arms extending from a common junction with some of the arms being provided with ultrasonic generators, at least one other arm carrying a bonding tool, especially for bonding a conductor to a chip and at least two of the arms including a straight angle of 180&#xb0; with one another.
