Description

The Prognostics and Diagnostics (P&D) Laboratory supports and conducts fundamental experimental P&D related efforts within the Army's Condition-based Maintenance (CBM) Enterprise. This facility houses state-of-the-art P&D hardware, software, and technical capabilities and contains a 22-kip Material Testing Systems (MTS) mechanical load frame with a high temperature furnace capable of exposing materials to temperatures over 2,700 degrees Fahrenheit. It also houses a state-of-the-art, customized, 16-channel high speed acoustic emission system; 64-channel acousto-ultrasonic piezo-based hardware; a high speed (500 KHz) 4-channel Fiber Bragg Grating interrogator unit; Digital Image Correlation (DIC) hardware capable of dynamic strain measurement up to 30 Hz; a hand-held phased array ultrasonic system; a dual mode eddy current system; an Agilient impedance analyzer capable of measuring up to 550 MHz; high speed oscilloscopes and other National Instrument data acquisition systems; Labview Software; a dual head piezoelectric and electromagnetic actuator; and several types of acoustic emission, ultrasonic transducer, Fiber optic, and piezo-based sensors. The P&D Lab supports prognostics health management research activities encompassing various research aspects of structural health monitoring and life prognosis; propulsion health monitoring; machinery and rotary dynamic components diagnostics and prognostics; physics, materials, electronics, advanced sensing, and data acquisition hardware; signal processing; data mining and fusion; and system health management and reasoning.
