Glass window vibrations analysis used for positioning of piezoelectric damping elements

Transfer of vibrations through a glass plate, mounted in a rigid frame, is investigated using an experimental setup consisting of set of microphones and 2D plane vibrometer. In particular, we aim at measurements of local amplitudes and phases of out-of-plane glass motion. Obtained data are combined, visualized and used for identification of positions on glass, which are most suitable for placement of damping piezoelectric elements for active vibration suppression.
