ABSTRACT:
An impactor for a movable, deformable barrier, simulating an automobile, comprising an upright, solid backing support, a plurality of energy absorbing impact segments protruding from the support, each segment having an outer impact face and each comprising a plurality of layers of honeycomb having different crush strength characterized by increasing crush strength of successive layers from the outer impact face to the support, the layers being separated by and secured to perforate plates therebetween allowing air flow from a crushing layer to the succeeding layers when the layers are successively crushed and each impact segment having a thin vent layer of noncrushing slotted honeycomb adjacent the support for discharge of air from all of the segments as they are successively crushed. The layers in each segment are of essentially the same width and height. The layers in each segment, except for the vent layer, are individually precrushed sufficient to eliminate the initial compression load spike, and portions of the precrushed faces of the honeycomb layers have recesses resulting in reduced physical face area. The recesses are preferably formed by precrushing.
