On the use of shunted piezo actuators for mitigation of distribution errors in resonator arrays

Abstract

Earlier work has shown that an array of very small attached resonators can be designed to alter the dynamic response of a primary structure. The altered response can be designed to make the primary structure appear heavily damped or to have a particular spectral shape such as a band- pass response. However, small errors in the distribution of mass and stiffness distribution of the attachments can have a significant effect, degrading the intended performance. This presentation discusses a concept of correcting small property distribution errors using shunted piezoelectric strip actuators bonded to the attachments.
