Abstract
A passenger car sized pendulum is supported by a moving pivot point. The moving pivot point is forced horizontally by the angular movement of the pendulum. By resisting the horizontal force the angular movement of the pendulum is reduced. The preferred embodiment for resisting the horizontal force is a parallelogram assembly supporting a horizontal support platform. The parallelogram assembly has a damping cylinder resisting the horizontal force.
Claims22
A pendulum damping apparatus comprising:
- a pendulum having a support line affixed to a moving pivot means;
- said moving pivot means having a horizontal vector of motion;
- and
- an externally powered damping means corrected to said pivot means and functioning to counter the horizontal vector of motion, thereby reducing the angular movement of the pendulum.

A pendulum damping apparatus comprising:
- a pendulum having a mass and a swing arc;
- a pendulum support line attached to the pendulum defining a radius of the swing arc;
- a horizontal platform functioning to support the pendulum support line;
- a pendulum support frame having a first and second horizontal end;
- a pair of parallel pivoting support arms depending from the pendulum support frame and pivotally affixed at each of the first and second horizontal ends of the pendulum support frame, thereby forming a parallelogram assembly among the pendulum support frame, the pair of pivoting parallel support arms, and the horizontal support platform;
- and
- a powered piston affixed to one horizontal end of the horizontal support platform, functioning to move the horizontal support platform, thereby lowering the pendulum mass out of sync with the pendulum swing arc, thus, damping the pendulum swing arc.

A pendulum damping apparatus comprising:
- a pendulum having an angular movement;
- a pendulum support line;
- a horizontal pendulum support frame having a first and second horizontal end;
- a damping vehicle having a wheel riding on the horizontal pendulum support frame and having a support means for the pendulum support line;
- and
- said damping vehicle further comprising an externally powered damping means functioning to reduce the angular movement of the pendulum.
