An apparatus for damping an actuator includes an inerter. The inerter includes a first terminal and a second terminal movable relative to one another and configured to be mutually exclusively coupled to a support structure and a movable device actuated by an actuator. The inerter further includes a threaded shaft coupled to and movable along the inerter axis with one of the first terminal and the second terminal. The inerter additionally includes a flywheel rotatable in proportion to movement of the threaded shaft in response to axial acceleration of the first terminal relative to the second terminal during actuation of the movable device by the actuator. The inerter reduces actuator-load-oscillatory amplitude at resonance of the actuator and movable device relative to the actuator-load-oscillatory amplitude that would otherwise occur using the same actuator without an inerter.
