Abstract
Official abstract text for this publication.
In the method for monitoring flexural vibrations of a piezoactuator, a small-signal spectrum of a piezoactuator, which is provided and mounted for the purpose of exciting longitudinal vibrations, is measured and an excitation of a transverse vibration in the piezoactuator is detected from resonances occurring in the small-signal spectrum.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for monitoring flexural vibrations of a piezoactuator, the method comprising: providing a mounting for the piezoactuator; applying an AC voltage exciting longitudinal vibrations in the piezoactuator; measuring a small-signal spectrum of the piezoactuator when the longitudinal vibrations are excited; monitoring an excitation of a transverse vibration in the piezoactuator from resonances occurring in the small-signal spectrum; and changi…
