After 10 years of well-functioning operation, it is time to refurbish the TMD’s on the pedestrian bridge Bagers Bro in Malmö.
The original TMD’s were designed by Vibratec and tuned to dampen frequencies in the range 1,6 to 2,15 Hz (corresponding to the resonance frequency of the bridge and the walking frequency). Now we re-paint the steel using offshore paint (to ensure better corrosion protection), refill the viscous oil and update the steel springs. Low frequency TMD’s are one of Vibratec’s specialities.
