This case study details research to maximise area coverage per sensor in permanently installed monitoring. It resulted in the development and patent of a new Location Specific Temperature Compensation (LSTC) method which, among other applications, has been trialled on a bulk ultrasonic wave monitoring system and shown to perform very well.
The research team at Strathclyde has been researching the use of robotics in NDE since 2006. Early work on small mobile robot platforms for delivering ultrasonic and magnetic flux leakage measurements was matured with NNL into an on-site inspection at Sellafield supporting Magnox reprocessing life extension in 2012. Subsequent work on mobile robotics concentrated on bringing classical robotic path planning and location systems (such as SLAM–simultaneous location and mapping) together with novel approaches using ultrasound to provide both NDE and path planning data.
The University of Bristol’s research in ultrasonic array technology applied to non-destructive testing has forever changed the way safety critical inspections are carried out and helped to extend the service life of valuable assets, boost revenue and improve safety in high-value engineering sectors such as nuclear and aerospace.
Developed by the University of Nottingham’s Optics and Photonics Research Group led by Professor Matt Clark, SRAS (Spatially Resolved Acoustic Spectroscopy) is a technique that can rapidly map the surface grain structure of materials, giving reliable and accurate data about shape, size and orientation of each grain.
