Shock Isolator Assembly for a Vehicle Mounted Payload

A shock isolator assembly comprises a base a platform and a plurality of self-resetting buckling isolators providing a three-stage response to a dynamic load acting between the base and the platform. The three-stage response of the self-resetting buckling isolators comprises a tension stage when the dynamic load exceeds a threshold tension load, a compression stage when the dynamic load exceeds a threshold compression load, and a rigid stage when the dynamic load is below the threshold tension load and the threshold compression load.
