Abstract
Passive piezoelectric damping devices are studied. These devices, consisting of a piezoelectric element and a resonant shunt, are analogous to mechanical damped vibration ab sorbers. In the past, a single piezoelectric device has been used to suppress a single structural mode. In this paper, the theory is expanded so that a single piezoelectric element can be used to suppress multiple modes. The multimode damper is demonstrated experimentally as a two-mode device ap plied to a cantilevered beam.
