This is a practical experiment using an inerter element to mechanically isolate vibration at a given frequency.

Summary[edit]

Description
English: The steel flywheel rotates only when there is relative motion between the two carriages (ie. if they are moving together, the flywheel doesn't rotate). The flywheel has rotational inertia - so it resists acceleration but not velocity or displacement but ONLY in relative motion (as opposed to masses which resist only their absolute acceleration). This is called an inerter and completes the trio of spring (relative displacement), damper (relative velocity) and inerter (relative acceleration). It's essentially just another component in the engineers toolkit to apply control to linear systems.
