Research Instrumentation for Investigating Vibration Delocalization and Control of Nearly Periodic Structures via Piezoelectric Networks

Abstract

The overall goal of this DURIP project is to acquire major facilities that are critical in the development of a comprehensive experimental testbed for advancing the technology of low vibration periodic structures (e.g., bladed-disk assemblies and satellite antennae). Some of the main hardware components include a laser vibrometer system, an isolation table, high-performance mid-range travel linear stages and motion controller, and a 6-channel power amplifier. The proposed new equipment will directly enhance the Principal Investigator's current AFOSR research program (Grant number F49620-01-1-0156). The research results will be useful for many Air Force applications, such as in space structures and jet engine fan/turbine blade structures (conclusion based on technical discussions with Wright-Patterson and Kirtland Air Force Research Labs).
