A tuned mass damper includes a damper mass having a first mass portion and a second mass portion connected by a third mass portion. The first mass portion, the second mass portion, and the third mass portion form a U-shaped configuration of the damper mass. The damper mass is configured to separate within the third mass portion in response to a force transferred to the damper mass of the tuned mass damper to allow relative motion between the first mass portion and the second mass portion. The damper mass may include geometric features that promote rotation of the tuned mass damper relative to an axis, when subjected to impact loads.

Vibration absorber

An apparatus includes a retainer, a rotational portion that is connected to the retainer so that it is able to rotate with respect to the retainer on a rotation axis, a rotor that is connected to the rotational portion for rotation in unison with the rotational portion, and a caliper assembly that is connected to the retainer so that the caliper assembly is able to move according to a line of action. The apparatus also includes a damper assembly that is connected to the retainer and is connected to the caliper assembly to regulate movement of the caliper assembly with respect to the retainer along the line of action, wherein the caliper assembly and the damper assembly cooperate to define a mass damper system that damps vibration of the rotational portion.

Vibration control system

A motion control system includes an absorber fixed relative to an axis, a spring fixed relative to the axis, and a mass coupled to the absorber and the spring and configured to move relative to the axis. The spring is configured to bias the mass toward a neutral position and with the absorber configured to dampen movement of the mass. The mass includes an internal surface and an external surface spaced from the internal surface. The external surface extends between a first end and a second end, with the first end closer to the axis than the second end. At least a portion of the external surface tapers away from the axis and toward the internal surface further from the first end to direct debris away from the axis.

Motion control system

A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

A mass damper system includes an unsprung mass, a sprung mass, a suspension component that supports the sprung mass with respect to the unsprung mass, and a damper mass that is connected to the unsprung mass. Motion control components are connected to the sprung mass and a fluid-operated system that transfers forces between the motion control components and the damper mass to regulate motion of the damper mass with respect to the unsprung mass.
