Electrorheological Material Based Smart Structures
Abstract
The present report contains the results of a three study conducted at Lehigh University into electrorheological (ER) material based smart structures. The program completed at Lehigh involved closely related and fully coupled investigations into ER smart structures testing and modeling, fiber-optic based in-situ structural vibration monitoring, and real-time neural network based vibration control. In order to facilitate the basic science advancements realized, five structural beam-like and platelike configurations were focused on throughout the project. For each of these configurations, a structural vibration model was developed and tested with corresponding experimentation. Novel fiber-optic sensors and neural network controllers were also developed, and in several cases these were implemented into ER based smart structure experiments to yield physical demonstrations of fully smart or adaptive structures. It was concluded that the concept of ER smart structures for Army applications remains promising and that the models developed can now be used to evaluate that promise. The development of improved and stronger ER materials in the future, however, is likely to required for many proposed applications of the technology.
