SELECT STRENGTH STEEL BUMPER SYSTEM

The SS Bumper is a new concept in automobile systems that achieves a very significant weight reduction in steel bumper construction and is capable of meeting the 5 mph FMVSS U.S. Government impact standard. It offers a low cost method of achieving a double digit weight reduction with no cost premium for aluminum or plastic materials. This paper concentrates on describing the configuration of the SS Bumper and a simple, easy to apply procedure for a car application which includes discrete equations for bending strengths, torsional strength and the new dent strength relationships which have been recently developed. One version of the SS Bumper applied to the 1983 Thunderbird is also described.
