System design for vibration analysis
Continuous monitoring of the structural integrity of buildings could help to detect premature aging or damage and guide an appropriate maintenance plan. These Structural Health Monitoring (SHM) techniques may include a data logger, several sensors and some processing capability. Vibration analysis in a structural assessment, using accelerometers (among other types of sensors), allows measuring the structural response and detecting changes in modal parameters (natural frequencies, damping ratios and modal shapes), giving clues about the existence of some kind of structural damage.
In this line of research we are working on the design, development and testing of a low-cost SHM system based on MEMS (Micro Electro-Mechanical Systems) triaxial accelerometers. We are working on the development of a new control system composed of a myRIO platform, managed by a specific LabVIEW software, which is also in charge of calculating the frequency response functions for the subsequent modal analysis.
