The result of many months’ work on an EPSRC funded project was revealed on 16th February at a launch event for a novel vibration control system. The event attracted directors, associates and senior engineers from major companies including WSP, Atkins, Foster and Partners and Arup. They witnessed the launch of a proof-of-product system, which was developed by Professor Paul Reynolds and Dr Emma Hudson to address the current gap between the proven academic successes of active vibration control for floor structures and the lack of adoption by industry to date.
The technology works in a similar way to that of popular noise-cancelling headphones: an accelerometer is used to measure the vibrations of the structure; the resulting signal is processed by a real-time computer and then an actuator generates the required force to cancel out the measured vibrations.
This new product combines all these components into one standardised compact unit that can be more easily installed within structures. Crucially, the system has been developed with robustness and minimised cost as priorities, to complement the proven high performance of this technology. In this way, the system is significantly more commercially attractive to potential adopters, meaning that the benefits of enhanced vibration performance are now a step closer to being realised.
A lunchtime seminar was organised at the Institute of Structural Engineers HQ in London to highlight the potential benefits of this new product to key industry contacts. A joint presentation by Paul Reynolds and Emma Hudson was followed by a live demonstration of the new system.
