Integrated Diagnostics; A DoD Multidisciplinary Research Program of the University Research Initiative

摘要

This document summarizes performance activity regarding basic research conducted in the area of Integrated Diagnostics, a term associated with the technologies and methodologies used to determine how mechanical failures occur, and how they can be detected, predicted and diagnosed in real-time. Objectives, set forth through the Department of Defense Multidisciplinary Research Program of the University Research Initiative (M-URI) have been addressed by faculty and staff from the Georgia Institute of Technology, Northwestern University and the University of Minnesota. Experiments based on material, load and vibration information from critical rotorcraft components have been conducted so as to collect data of relevance in understanding the mechanisms of failure for use in developing failure models. These models can serve as a guide in the selection and development of sensors to detect faults and pending failures. Effort has been placed on microsensor development, and achieving the means to analyze and correlate reliable sensor output for remaining life estimation and operator use. Organizationally, this activity is being accomplished through (13) projects, categorized by three thrust areas.
