Title:
DYNAMIC DAMPER, VIBRATION ISOLATOR, AND METHOD FOR MANUFACTURING MAGNETIC VISCOUS ELASTOMER
Document Type and Number:
WIPO Patent Application WO/2016/148011
Kind Code:
A1
Abstract:
This dynamic damper is provided with a movable part (17) that can be moved by external input, and an excitation coil (14) for generating a magnetic field of an intensity corresponding to a supplied electric current. The movable part (17) is configured to include: first and second magnetic cores (11), (12) in which magnetic paths, which are pathways for the magnetic field generated by the excitation coil (14), are configured as annular closed magnetic paths; and a magnetic viscous elastomer (13) of which the viscous properties change in accordance with the size of the magnetic field generated by the excitation coil (14). The magnetic viscous elastomer (13) is arranged so as link at least one location in the first and second magnetic cores (11), (12) and constitute a closed magnetic path.
