When it comes to constructing lightweight structures, there are numerous benefits, such as using less material. However, one common issue with lightweight floor systems is that they tend to vibrate significantly at low frequencies. This vibration generates a lot of noise in the room below, causing annoyance. To address this problem without adding excessive weight, dynamic vibration absorbers (DVAs) could be the solution.
In a recently published paper (https://lnkd.in/enxfHwRY), Qin Yi, Jin Jack Tan and Maarten Hornikx introduce a methodology that allows for the quick prediction of vibrations in a joist floor, whether DVAs are included or not. This methodology builds upon an existing analytical model for lightweight floors. We present a comparison between this model, reference calculations, and measurements conducted in our laboratory at Eindhoven University of Technology using a scaled floor system equipped with DVAs.
In summary, our method is now ready to optimize the vibration damping of floor systems using DVAs. Stay tuned for more exciting developments in this field!
