Abstract

An example cantilever assembly includes a cantilever including an anchor configured to be coupled to a support, a tip, and an arm positioned between the anchor and the tip, a hollow conductive tube positioned at the tip of the cantilever, and a magnet suspended inside the hollow conductive tube with a first spring and a second spring. The first spring and the second spring are positioned at a first end and a second end of the hollow conductive tube respectively, and the magnet is positioned between the first spring and the second spring. The magnet is configured to move coaxially inside the hollow conductive tube as permitted by the first spring and the second spring, and the magnet suspended inside the hollow conductive tube operates as a tuned mass damper (TMD) to limit a resonant response of the cantilever assembly.
