Abstract
A passive motion isolation system for motion-sensitive equipment is disclosed. The passive motion isolation system has a three-axis free motion platform mounted on a base subject to ambient motions. A vibration isolation subsystem is coupled between the motion-sensitive equipment and the three-axis free motion platform.
Claims16
A motion isolation system for motion-sensitive equipment, comprising:
- a base subject to ambient motions;
- a three-axis free motion platform mounted on the base, the three-axis free motion platform coupled with the motion-sensitive equipment, the three-axis free motion platform comprising:
- a first axis carriage free to move along a first axis rail,
- a second axis carriage free to move along a second axis rail,
- a third axis carriage free to move along a third axis rail, each of the first axis rail, the second axis rail, and the third axis rail having a finite length between respective ends;
- and
- a vibration isolation subsystem counterbalanced in an upward direction by two constant force springs positioned on opposite sides of the third axis rail, the vibration isolation subsystem comprising:
- a support plate attached to the third axis carriage;
- four elongate resilient pillars, each elongate resilient pillar having a first end affixed to the support plate, a length extending from the support plate parallel to a vertical axis, and a second end;
- and
- a mounting bracket to couple the motion-sensitive equipment to the second ends of the four elongate resilient pillars,
- wherein the two constant force springs are non-overlapping with the third axis rail in the upward direction,
- wherein the two constant force springs are overlapping with the support plate in a horizontal direction, and
- wherein the three-axis free motion platform is coupled with the motion-sensitive equipment via the vibration isolation subsystem.
