Health monitoring of large structures
This article describes a damage detection and health monitoring method that was developed for large space structures using on-orbit modal identification. After evaluating several existing model refinement and model reduction/expansion techniques, a new two-step approach was developed to identify the location and extent of structural damage with a limited number of measurements. A general area of structural damage is first identified and, subsequently, a specific damaged structural component is located. Performance of the proposed damage detection approach was demonstrated with test data from two different laboratory truss structures. This dual-use space technology can potentially be applied to structural inspection of aircraft, offshore platforms, oil tankers, bridges and buildings. In addition, its applications to model refinement could improve the design of structural systems such as automobiles and electronic packaging.
