ABSTRACT:
An energy absorbing device for use alongside a roadway to decelerate an impacting vehicle includes first and second elements. The first element extends in an axial direction and includes a threaded portion that defines a multitude of projecting ridges. The second element is movable relative to the first element in the axial direction, and the first and second elements are sized to create an interference fit such that relative axial movement of the second element applies a shear load to the first element to progressively deform successive ones of the projecting elements. This progressive deformation of the projecting elements retards relative axial movement between the first and second elements.
