Nettet18. mai 2015 · The vibration being amplified could originate from a number of sources: unbalance, misalignment, pump vane vibration – almost any source of vibration can cause resonance. And that vibration does not have to be a problem in itself. For example, resonance can cause slight unbalance to appear as if the rotor is seriously out of balance. NettetA tuned mass damper (TMD), also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce mechanical vibrations, consisting of a mass mounted on one or more damped springs. Its oscillation frequency is tuned to be similar to the resonant frequency of the object it is mounted to, and reduces the object's …
