Experimental Intelligent Structures

Abstract

This instrumentation grant requested equipment to establish an Intelligent Structures Laboratory for the R&D of cybernetic or artificially intelligent structures. The equipment requested included a mechanical testing machine, signal processing instrumentation, piezoceramic materials, software for a laser vibrometer, oscilloscopes, and other instrumentation. Experimentation was performed using some of the equipment purchased in this grant. Salary support for the research was from other research grants. The equipment purchased will be the basis for long-term experimental research in the area of intelligent structures. The equipment and instrumentation requested was ordered and received and all is operating except for the mechanical testing machine which is being installed. Analytical studies and simulations of intelligent structures and no-load testing of an artificial neural system are being performed and some interesting results from these activities are highlighted in this report. The next step in the work is to test an artificial neural system under loading using the mechanical testing system. The intelligent structure to be tested is a composite component with the neural system attached. The structure will be tested under realistic load conditions to verify that the neural system can detect initiating damage in the panel. Further studies will be to develop the algorithms and the sensor system architecture needed to provide strain and acoustic emission information that can be used to optimize the performance while minimizing the fatigue of the structure. Development of a self-regulating or intelligent structure that can sense and optimize its performance while minimizing fatigue damage is the goal of this research.
