Structural Health Monitoring of Strategically Tuned Absolutely Resilient Structures (STARS)

摘要

Strategically Tuned Absolutely Resilient Structures (STARS) are being designed to store potential energy in the form of elastic deformation that can be released in a controlled fashion as work or kinetic energy. This paper outlines steps being taken to monitor the structural health of STARS by making modifications to a Remote Readiness Asset Prognostic and Diagnostic System (RRAPDS). The latter is being developed by the U.S. Army Aviation and Missile Command Research, Development and Engineering Center (AMRDEC)/U.S. Army Tank Automotive and Armaments Command, Armaments Research, Development and Engineering Center (TARDEC) to monitor health/condition and deliver advanced diagnostics/prognostics while an asset (i.e., missile) is tactically deployed, in storage, and/or being transported. As an example of this application, it is described how and why accelerometers are being redesigned to quantify the dynamic performance of 'ConQuest,' Team UAH's entry in the 2004 ASCE/MBT National Concrete Canoe Competition.
