Abstract: A gas spring for suppression vibrations in payloads is provided. The gas spring comprises a piston disposed within the housing. The piston is configured to be displaced relative to the housing in response to vibrations applied to the housing. The piston has first concave or convex surface and a second surface opposing the first surface. The housing is configured to allow a first gaseous medium to apply a first gas pressure to the first concave piston surface, and 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.

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.

Abstract: Vibration suppression systems and methods for isolating payloads from vibrational forces are provided. A gas spring has a housing and a piston within the housing. The piston is mechanically isolated from the housing via a magneto-rheological (MR) fluid gasket. 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. A magnetic field is selectively applied to the MR fluid gasket to alternately transform the properties of the MR fluid gasket between primarily viscous and primarily elastic.
