Vibration Sensing System for Structural Health Monitoring Experiments
Abstract
In support of ONR Grant # ONR N00014-20-1-2478, entitled Passive Structural Health Monitoring (SHM) With a Sparse Sensor Set, the,Marine Physical Laboratory proposes to construct a direct vibration sensing system to augment our existing acoustic holography capab,ilities. This equipment will consist of an array of miniature accelerometers that can be directly applied to a target model structu,re for observing the bodys response to given stimuli provided by direct excitation from controlled shakers. This data set, collecte,d both with and without the presence of introduced model defects, will allow us to detect and localize structural damage using match,ed field techniques, and is directly applicable to the problem of real-time submarine structural health monitoring utilizing a spars,e set of embedded sensors. A single-point laser doppler vibrometer will augment our existing scanning laser equipment to provide add,itional non-contact ground-truth measurements of the SHM laboratory experiments.This abstract is publicly releasable.
