Structural Integrity Monitor

SIMS is an automated instrument for detection and diagnosis of structural faults using vibration signature measurements. An array of piezoelectric transducers attached to the structure are used for both actuation and sensing.

SIMS actively excites the structure with wideband energy (up to 100 kHz). Statistical analysis of the changes in the vibration signature is used to detect, localize, and assess the severity of damage in the structure. SIMS can detect small, incipient damage without time consuming and expensive inspection procedures.

Applications

• In Situ NDE System
• Structural Vibration monitoring
• Inspection of metal and composite parts
• Diagnosis for condition based maintenance

Features

• Integrated wideband vibration signature analysis system for structural integrity assessment
• Piezoelectric sensors are bonded/ embedded in structure
• Uses powerful pattern recognition to identify structural degradation
• Damage detection cracks delaminations disbonds impact damage
• Modular system architecture can be configured for any application
• Stand-alone unit or can be integrated into a comprehensive health monitoring system such as an aircraft HUMS
