Abstract

The active/passive absorber for extended vibration and sound radiation control includes principally two layers (402) the first layer has a low stiffness per unit area which allows motion in the direction perpendicular to its main plane. The second layer is principally a mass layer (400’). These two combined layers have a frequency of resonance close to one of the main structure. The dynamic behavior of the coupled system makes the active/passive absorber a passive absorber; however, the first layer can be electrically actuated to induce motion in the direction perpendicular to its main plane. This additional property induces and/war changes the motion of the mass layer and therefore improves the dynamic properties of the active/passive absorber system. The absorber can be provided as multiple layers.
