Motion-damping systems and methods including the same

摘要

MOTION-DAMPING SYSTEMS AND METHODS INCLUDING THE SAME Motion-damping systems (100) and methods that include motion-damping systems (100) are disclosed herein. The motion-damping systems (100) are configured to damp relative motion between a base structure (21) and an attached component (40) that define a gap (80) therebetween. The systems (160) include an at least substantially rigid tubular structure (110) that defines an internal volume and extends within the gap (80). The systems (100) also include a magnetic assembly (140) and a magnetically active body (170). One of the magnetic assembly (140) and the magnetically active body (170) is located within the tubular structure (110) and the other of the magnetic assembly (140) and the magnetically active body (170) is operatively attached to a selected one of the base structure (21) and the attached component (40). The magnetic assembly (140) is in magnetic communication with the magnetically active body (170) such that a magnetic interaction therebetween resists motion of the attached component (40) relative to the base structure (21). The methods include dissipating energy with the motion damping system (180). 26 40 22 20 46 48 24 100 54 28 30 44 50 00000000000000000000 2 4 000000000000000 ~ ~~~0000000000000000 .0,, .. 0 " Fig. 1 18 100 _ 20 40-- 110 114060 144 - A132 1 12--,- 146 ~ ---112 t--------------/------- I ' 120'' 170 174 170i172 80o Fig. 2
