Abstract

Title: Influence of Confined Vibrations on Sensor and Actuator Optimization

Author: Daryoush Allaei (QRDC, Inc.) and Yin-Tsan Shih (QRDC. Inc.)

The purpose of this paper is twofold. First, to report on a preliminary study conducted to determine the effect of confined vibrations on the sensor and actuator optimization based on their location and number. Second, to introduce a preliminary design methodology to incorporate the confined modes in the design stage of the sensor/actuator arrays for smart structures. Based on our results, it is clear that modal confinement has a significant impact on the optimization of sensors and actuators. Our modified optimization procedure and design methodology have proven to be effective in addressing the related issues.
