STRUCTURAL HEALTH
INTRODUCTION
Structural Health Monitoring / Management (SHM) is a complex process of
  • design, development and execution of damage identification,
  • localization and quantification strategy for aerospace, civil, marine, and mechanical engineering infrastructure
  • involving multidisciplinary domain expertise, encompassing fields such as structural dynamics, signal processing, motion and environmental sensing hardware, computational hardware, data telemetry, smart materials and statistical pattern recognition, as well as other fields.
Non-destructive testing and evaluation of the deflection and vibration parameters, play an important role in the health monitoring of structures.
Against the backdrop of this dire need for remote and accurate monitoring of vibrational displacements, velocities and accelerations; for various applications across all industries, we have designed and developed innovative photonic systems - VEDA and VIDUR (patents pending) capable of monitoring real time vibrations on structures (bridges, platforms and highways) from remote locations.

FUNCTIONAL OBJECTIVES
  • VEDA and VIDUR are indigenously designed and developed photonic technologies with high sensitivities and accuracies, free of the many limitations encountered by the existing conventional technologies of today.
  • The systems are low powered, compact, portable and can easily be deployed at any location for real time vibration and condition monitoring in a non-intrusive fashion, even for monitoring inaccessible locations on structures.
  • The innovative technologies and the algorithms employed in the development of the systems ensure the real time extraction of the following information :
    • Vibration and Condition of Structures/Bridges/Highways.
    • Vehicular and Pedestrian Traffic Statistics on a Bridge.
    • Vehicular Identification (Type, Size Tonnage and Number)
    • Structural Health Diagnostics.
    • Intrusion Detection
ATTRIBUTES
  • Vibrational displacements, velocity and acceleration parameters can be simultaneously extracted in real time in both time as well as frequency domains from remote locations, non-intrusively.
  • The new photonic systems and technologies, in addition to being market ready have also been integrated with technologies using fundamental communication concepts of Internet of Things (IOT) for integrating spatially separated systems with a cloud server for quick deployment in the field.
  • The systems are compact, portable and can be easily deployed at any location for real time vibration and condition monitoring in a non-intrusive fashion, even at inaccessible locations.
  • The present systems are capable of remotely monitoring vibrations and condition of structures simultaneously in the time and frequency domains with high sensitivity.
  • Technologies for integrating various spatially separated systems using fundamental communication concepts of Internet of Things (IoT) are also in place for quick deployment.
ENABLER
  • The innovative technologies and the algorithms employed in the development of the system ensure the real time extraction of the following information :
    • Level 1 : Detection- VIDUR AND VEDA simply answers the question: is there a damage?
    • Level 2 : Localization- VIDUR AND VEDA is capable of specifying the location of the damage within the structure
    • Level 3 : Assessment- VIDUR AND VEDA is capable of specifying the type and extent of damage
    • Level 4 : Prediction- VIDUR is capable of estimating the remaining useful life (RUL) and safety.
