1. An isolation system comprising:
a buckling beam comprising a first end and a second end;
a first restraining mechanism comprising a first elastomeric material engaged with the buckling beam, the first restraining mechanism being configured to move between a first position and a second position to variably control a first restraining condition of the buckling beam and to thereby affect a negative stiffness of the buckling beam; and
a payload mount coupled to the buckling beam at one of the first end, the second end, and a location between the first end and the second end,
wherein the payload mount is coupled to the buckling beam using the first restraining mechanism,
wherein the payload mount comprises a linear bearing configured to enable a payload to move relative to the first restraining mechanism, and
wherein the distance between the first position and the second position is based on compression stiffening of the first elastomeric material.
