Abstract
A vehicle mounted crash attenuator includes an array of parallel diaphragms. A set of cell assemblies is interposed between adjacent diaphragms, and each cell assembly is formed of two L-shaped sheet metal components which are riveted together to form a rectangular column extending between the adjacent diaphragms. These columns are cross braced by ribbed braces which extend diagonally between adjacent columns. These cross braces stabilize the columns against long column buckling and promote short column buckling, thereby increasing the energy absorbing capability of the columns.
