Abstract
Vibration damping devices and methods utilizing the same for damping vibrations in a fan. A vibration damping device for a fan, the fan having an inlet side of a frame and an exhaust side of the frame and the frame retains a fan mechanism. The vibration damping device includes a mass mT which may include either: a block with a total mass mT; or a finger guard and at least one resilient attachment member having a first spring characteristic, wherein resilient attachment member is configured to be connected to and retain the mass mT. The vibration damping device may be tunable to damp the vibration of fan by (a) varying the total mass mT of the block, or replacing the finger guard, and/or (b) replacing the at least one resilient attachment member with a second resilient attachment member having a second spring characteristic.
