Abstract
An active damping system for use in connection with a vibration isolation system includes an intermediate mass between a base and an isolated payload. The intermediate mass is supported by at least one support element which also supports at least substantially all of the static forces of the isolated payload. An actuator dampens and isolates dynamic forces acting on the intermediate mass from the isolated payload. The active damping system also includes a payload support element and a passive damping element, both of which are coupled at one end to the payload platform and at an opposite end to the intermediate mass. A sensor is affixed to the intermediate mass to generate a feedback signal to a processor coupled to the actuator.
Claims23
An active damping system positioned between a base and an isolated payload that generates a static force, said active damping system comprising:
- an intermediate mass;
- a payload support element extending between the isolated payload and said intermediate mass, said payload support element configured to support the isolated payload on said intermediate mass;
- an intermediate mass support element extending between said intermediate mass and the base, said intermediate mass support element configured to support at least substantially all of the static force of the isolated payload;
- an active damping actuator having one end adjacent to said intermediate mass and an opposite end adjacent to said base;
- a first sensor affixed to said intermediate mass, said first sensor configured to generate a first signal responsive to movement of said intermediate mass caused by dynamic forces;
- and
- a compensation module coupled to said first sensor and said active damping actuator, said compensation module configured to respond to said first sensor signal by dampening said dynamic forces acting on said intermediate mass through actuation of said active damping actuator to isolate said dynamic forces from the isolated payload.
