The use of piezoelectric materials simultaneously as passive modal devices and active elements to suppress structural vibrations is discussed. A simple modal model is developed which predicts the behavior. Experimental studies are then conducted to verify the model. The results show a reduction of 20 dB in the second mode of the structure is possible via passive shunting while simultaneously commanding the piezo-actuator. The results indicate that for vibration problems involving a few modes, piezoelectric devices combining active and passive techniques can significantly reduce the broadband structural response to disturbances.
