Abstract
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.
Claims21
A mass damper system, comprising:
- an unsprung mass;
- a sprung mass;
- a suspension component that supports the sprung mass with respect to the unsprung mass;
- a damper mass that is connected to the unsprung mass;
- motion control components that 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,
- wherein the motion control components include a spring and at least one of a damper or an actively controlled actuator that apply a resultant force in opposition to an inertial force from the damper mass.

A vehicle, comprising:
- an unsprung mass;
- a sprung mass;
- a suspension component that supports the sprung mass with respect to the unsprung mass;
- a first fluid-operated cylinder;
- a damper mass that is connected to the unsprung mass by the first fluid-operated cylinder, wherein the damper mass applies an inertial force to the first fluid-operated cylinder;
- a second fluid-operated cylinder;
- a spring that is connected to the second fluid-operated cylinder;
- a damper that is connected to the second fluid-operated cylinder, wherein the spring and the damper cooperate to apply a resultant force to the second fluid-operated cylinder;
- and
- a fluid carrying connection between the first fluid-operated cylinder and the second fluid-operated cylinder that transfers the inertial force and the resultant force between the first fluid-operated cylinder and the second fluid-operated cylinder to regulate motion of the damper mass with respect to the unsprung mass.
