Integrated Diagnostics
Abstract
This document summarizes activity concerning the performance of basic research being 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 a Department of Defense Multidisciplinary Research Program of the University Research Initiative (M-URI), are being addressed by faculty and staff from the Georgia Institute of Technology, Northwestern University, and the University of Minnesota. Fourth year accomplishments and plans are reported upon. During this reporting period, experiments based on material, load, and vibration information from critical rotorcraft components continued so as to collect data of relevance in understanding the mechanisms of small crack growth for use in developing fatigue failure models. Such models serve as a guide in the selection and development of sensors to detect faults and pending failures. Effort has been placed on sensor development, and achieving the means to analyze and correlate reliable sensor output for operator use. Organizationally, this activity is being accomplished through (11) projects, categorized by the thrust areas of (1) Mechanical System Health Monitoring, including microsensor development and the condition monitoring of rotordynamic elements; (2) Nondestructive Examination Technology; and (3) Material Failure Characterization and Prediction Methodology.
