    Abstract: A multi-axis isolator configured to isolate a payload from unwanted vibrations and shocks includes a housing, at least one pair of radial isolators in the housing, and an axial isolator in the housing. Each radial isolator includes an elastomer dome, a chamber at least partially defined by the elastomer dome, and a fluid in the chamber. The multi-axis isolator also includes a fluid track placing the chambers of the radial isolators in fluid communication with each other. The axial isolator includes an elastomer dome, a backpressure membrane, a primary chamber, a backpressure chamber, a fluid in the primary and backpressure chambers, a conduit placing the primary chamber in fluid communication with the backpressure chamber. The multi-axis isolator also includes a shaft configured to be connected to the payload. The pair of radial isolators and the axial isolator are coupled to the shaft.

    Abstract: An isolator configured to isolate a payload from unwanted vibrations and shocks. The isolator includes a housing having a first end and a second end opposite the first end, a primary chamber defined in the housing, a backpressure chamber defined in the housing, a conduit placing the primary chamber in fluid communication with the backpressure chamber, a backpressure membrane in the housing proximate the first end, an elastomer dome in the housing proximate the second end, and a shaft connected to the elastomer dome. The primary chamber and the backpressure chamber are between the backpressure membrane and the elastomer dome. The shaft is configured to be connected to the payload.

    Abstract: A nonlinear mechanical element including a buckling column and hard stops. In one embodiment when the nonlinear mechanical element is subjected to an increasing compressive load, the buckling column buckles at a critical load, resulting in reduced stiffness past the critical load. One or more lateral hard stops may be provided adjacent to the buckling column to prevent the buckling deformation from exceeding a certain extent, and axial hard stops may be provided to shift the load path away from the buckling column when a certain amount of compressive displacement has been reached.

    Abstract: In one embodiment, provided is an actively tunable acoustic attenuator having a frame, a membrane within the frame, and a mass secured to the membrane. In another embodiment, provided is an actively tunable acoustic attenuator having a frame, a membrane within the frame, and a mass secured to the membrane. The membrane is coupled, either indirectly or directly, to the frame via a variable stiffness coupler. In another embodiment, provided is an actively tunable acoustic attenuator having a frame and a plurality of membrane layers within the frame. An active material is between at least two of the plurality of membrane layers. A mass is secured to at least one of the plurality of membrane layers.
