Description

WiBRATE explores new paradigms for developing innovative strategies for wirelessly monitoring and controlling vibration using a network of intelligent embedded devices that power themselves using harvested vibration energy [1,2]. The possibilities that that Wireless Sensor Networks (WSNs) offer to vibration monitoring and control are explored on challenging cases such as: 

  • Helicopter Rotor Blade (LMS) [3]
  • Car Assembly Line (Fiat)
  • Gas Turbine (Honeywell)
  • Train Bearings (Perpetumm)C:\Users\SanchezA\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Word\helicopterblade.jpgThe introduction on WSNs for condition monitoring promises significant advancements compared to traditional technologies. These possibilities are highlighted by the different case studies. For instance, the autonomy to place sensors on traditionally inaccessible locations is exploited for rotating blades as in the helicopter main rotor. Another feature of WiBRATE refers to the distributed sensing capabilities and synchronization aspects, relevant aspects for capturing the dynamic characteristics of the structures as in getting the vibration snapshot.
    The necessary synergies for high frequency sampling and communication speeds have been investigated at the case of gas turbines, for which real time feedback is necessary on compressor vibration control. The most advanced implementation of wireless vibration surveillance has been achieved for train bearings, which have been proven a reliable tool not only for maintenance reasons, but for railroad diagnostics. The adaptability of wireless sensor network to complex environments is tested for an actual car assembly line where all electromagnetic noise present challenges for the wireless communication [4].iStock_000016519692Medium.jpg
