VIBRATION In a world filled with energy and movement, unintended vibrations can cause products to malfunction and structural components to collapse. As such, vibration testing forms a major part of quality assurance in today’s products. Housing a suite of testing facilities, measurement and analytical tools, our capabilities extend beyond regulatory qualification testing and unearth vibration-induced damage and determine physical limits. Analyse Test - Vibration fatigue damage - Product screening and assessment evaluation - Identify operating and - Basic, mixed-mode & shock destruct limits excitations - Field Data Replication Monitor - Fault detection & health monitoring - Vibration & modal measurements Page - 9 // Reliability & Characterisation Unit

NON- DESTRUCTIVE EVALUATION Non-destructive evaluation (NDE) plays an important role not only in structural diagnosis, but also in assuring the continued serviceability of a system through structural health prognosis. Different NDE approaches are utilised to detect different types of anomalities.
