DYNAMIC EQUILIBRIUM AIR SPRING FOR SUPPRESSING VIBRATIONS
First Claim
1. A method of using a gas spring to isolate a payload from vibrational forces, the gas spring having a housing and a piston disposed within the housing, the piston having opposing first and second surfaces, the housing having a first chamber adjacent the first piston surface, the method comprising:
- coupling the payload to the piston;
applying a net gas pressure force to the piston by respectively exposing the first and second piston surfaces to first and second gas pressures;
allowing the piston to be displaced relative to the housing in response to a vibration applied to the housing, whereby the net gas pressure force is modified; and
modifying the mass of a gaseous medium within the first chamber to equalize the net gas pressure force.

Abstract
Vibration suppression systems and methods for isolating payloads from vibrational forces are provided. A gas spring has a housing and a piston disposed within the housing. The piston has opposing first and second surfaces, and the housing has a chamber adjacent the first piston surface. A payload is coupled to the piston, and net gas pressure force is applied to the piston by respectively exposing the first and second piston surfaces to first and second gas pressures. The piston is allowed to be displaced relative to the housing in response to a vibration applied to the housing, whereby the net gas pressure force is modified. The mass of a gaseous medium within the chamber is modified to equalize the net gas pressure force.

17. A vibration suppression system, comprising:
a gas spring including a housing and a piston disposed within the housing, the piston configured to support a payload and having first and second opposing surfaces, the housing having a first chamber for receiving a first gaseous medium that applies a first gas pressure to the first piston surface, the housing configured to allow a second gaseous medium to apply a second gas pressure to the second piston surface, thereby resulting in a net gas pressure force applied to the piston, the piston configured to be displaced relative to the housing in response to a vibration applied to the housing, whereby the net gas pressure force is modified; and a pressure control subsystem configured to modify the mass of the gaseous medium within the first chamber to equalize the net gas pressure force. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
