SCM 027

Prognostics and Diagnostics Laboratory

• Acoustic Emission System ‒ 16-channel, low frequency, ultrasonic conditioning unit‒ Frequency Range: 1.6 kHz to 40 MHz ‒ Up to 10 MHz sampling rate‒ Detect cracks and crack locations in structural components;

detect fiber breaks and delaminations in composites

‒ Acellent’s ScanSentry and ScanGenie II diagnostic unit generates and captures signals from piezoelectric sensors and actuators using Lamb waves

‒ Able to actively interrogate metallic and composite structures in-plane and out-of-plane

• Lamb Wave Diagnostics

• Impact Modal Analysis‒ Adapts to FFT analyzers for structural behavior testing‒ 0–5,000 lb/ft impact loading‒ x1, x10, x100 gain signal conditioning

‒ High speed interrogator capable of monitoring and analyzing FBG sensors with up to 4 channels simultaneously

‒ Up to 500 kHz for a single channel of 100 kHz on four simultaneous channels

‒ Sensitivity of 0.02 µe for periodic vibrations

• High-Speed Optical Sensing
