ENHANCED MAGNETIC VIBRATION DAMPER WITH MECHANICAL IMPEDANCE MATCHING

摘要

Magnetic vibration damper comprising three coaxial elements: a first coaxial element (1) with first permanent magnets (11), a second coaxial element (2) with first soft magnets (21) and a third coaxial element with second permanent magnets (31). The first soft magnets (21) are between the first permanent magnets (11) and the second permanent magnets (31) in a radial direction, and the spacing of the second permanent magnets (31) is larger than the spacing of the first permanent magnets (11). The damper further comprises energy conversion means, such as conductive layers (4) or coils (8) to convert the mechanical movement of the magnets into heat or electric current.
