A triaxially-equalized action shock and vibration-insulation mount is provided for the protection of a dynamic load-sensitive component, such as a mass-storage device, from external multidirectional dynamic loads above a predetermined magnitude. A substantially uniform, attenuated response of the component to such dynamic loads is the result, regardless of the direction of application of the loads. In order to achieve substantially uniform reactions to such external loads applied along any of the three orthogonal spatial axes, and further in order to achieve higher structural integrity of the mount by reducing flexural, tensile and/or shear stresses, the shock mount comprises a body of elastic, preferably foamed elastomer material, which is confined at its periphery in a rigid, stationary shell, substantially symmetrical relative to the orthogonal spatial axes and partially open at one side. The elastic material body is shaped at its geometrical center to provide a tight, e.g., spherical, socket for an enlarged symmetrical, e.g. spherical, end portion of a rigid rod extending outward from said socket, through the partially open side of the shell, into rigid connection with the load-sensitive component. The elastic material of the body is stressed primarily in compression along each of its axes. The elastomeric material may alternatively be constituted by a plurality of relatively small-diameter tightly randomly packed, solid elastic spheres.
