Title: Dynamic vibration absorber using magnetic spring and damper

This paper describes a dynamic vibration absorber based on a magnetic spring and damper system. A pair of double cylindrical magnets face each other across a gap, with one magnet fixed to the target structure and the other to the moving mass of the dynamic vibration absorber. The magnetic restoring force characteristics of the proposed system are examined through static loading tests and analysis. The dynamic characteristics are also tested in vibration tests. Furthermore, application of the proposed dynamic vibration absorber to a rotating machinery model demonstrates that the system gives effective two-dimensional vibration control.
