A Stereo-Triangulation Approach to Sensing for Structural Identification
Additional Document Info
Identification of large space structures distributed mass, stiffness, and energy dissipation characteristics poses formidable analytical, numerical, and implementation difficulties. Structural identification is crucial for implementing active vibration suppression concepts which are under widespread study in the large space structures community. Near the heart of the identification problem lies the necessity of making a large number of spatially distributed measurements of the structures free and/or forced vibratory response, with sufficient spatial and frequency resolution, and without introducing unwieldy sensor and actuator calibration requirements which are potentially more difficult than the structural identification problem.
