Vibration Control - Tuned Damper
Tuned Damper Prediction

In a recent project, Navcon & Halvorsen engineers encountered a 18 Hz resonance problem in a Drive Motor System. Various vibration control measures were investigated. Based upon the results of a sensitivity analysis it was determined that the optimal solution would be the installation of a tuned vibration damper. The following Graphs show the Frequency Response (Left) and the Operating Vibration Spectra (Right) recorded both without (Red) and with (Blue) the production Tuned Damper. The Drive Motor operates between 0 Hz. and 40 Hz. The vibration response of the Drive Motor System at 18 Hz was reduces by a factor of four (4).
