Abstract:
Earlier work has shown [J. Acoust. Soc. Am. 126, 1 (2009)] that the time and frequency responses of a lightly damped oscillating structure can be tailored by attaching an array of much smaller subordinate oscillators. Exact analytic governing equations of motion are used to describe the behavior of the coupled system that is composed of the primary system and the subordinate array. Further, it is shown that this tailoring can be achieved using a relatively small number ( & lt;100) of attached oscillators whose total mass is small (∼ & lt;1%) relative to the primary structure. This presentation will show how disorder in the property distributions within the array of attachments affects the tailored responses. Then with this general understanding, applications including time domain step response manipulation, bandpass filtering, and multianalyte detection based on dynamic response of microcantilevers are discussed. These examples represent case studies where sensitivity to disorder is either an asset or an encumbrance.
