30 % Mass Reduction acquired by Lightweight Steel Twist Beam

London (Scrap Monster) : Furthering its mission to help automakers meet stringent fuel economy requirements, the Steel Market Development Institute’s (SMDI) Automotive Applications Council unveiled the results of its lightweight steel twist beam study today. The project resulted in a 30 percent mass reduction at a significantly lower cost compared to designs using alternative materials. SMDI is a business unit of the American Iron and Steel Institute.
“With fuel economy regulations increasing rapidly, automakers are looking for every way they can to take weight out of vehicles,” said Ronald Krupitzer, vice president, automotive market, SMDI. “The lightweight steel twist beam project is a great example of how currently available advanced steel technologies enable aggressive weight savings in the vehicle’s suspension, thus enabling better fuel economy for the automaker and the consumer.”
The results of the study indicated that the selected “U-Beam” design – based on a tubular shape using advanced steels – achieves a 30 percent mass reduction relative to the baseline assembly, at a modest 15 percent cost increase, considerably less than the cost of similar weight savings from materials like aluminum.
