VARIABLE STIFFNESS APPARATUS FOR USING MEGNETO-RHEOLOGICAL ELASTOMER

摘要

The present invention proposes a variable stiffness device using a magnetorheological elastic body. A variable stiffness device using a magnetorheological elastic body according to an embodiment of the present invention includes a central axis iron core; An external iron core concentric with the central axis iron core; An upper iron core connecting the central axis iron core and an upper surface of the outer iron core; An iron core portion including a lower iron core connecting the central axis iron core and a lower surface of the outer iron core; A first magnetic rheological elastic body inserted along a horizontal cross-section of the central axis iron core; A second magnetic rheological elastic body inserted along the horizontal cross section of the outer iron core; And a central coil wound around the central axis iron core, wherein magnetic flux induced along the central axis iron core by a current applied to the central coil is a magnetic rheological elastic body inserted into the central axis iron core, the upper iron core, and the Via an outer iron core, a magnetorheological elastic body inserted in the outer iron core, and the lower iron core.
