Metalforming Technology Critical to the Future Steel Vehicle
“Because of steel’s flexibility, we were able to produce a broad bandwidth of solutions, all of which were evaluated on the basis of cost versus weight and CO2 equivalent emissions,” said Shaw. “Within this portfolio of solutions are applications that all vehicle manufacturers and segments will find relevant.”
The FSV is achieving its results through the use of a broad range of available steel grades and a design-optimization process that develops non-intuitive solutions for structural performance, including optimized shapes and component configurations. FSV’s steel portfolio is utilized during the material selection process with the aid of full vehicle analysis to determine material grade and thickness optimization.
A “Mass Paradigm Shift” Coming
The design and development process was expedited, we learned, by use of the Accelerated Concept to Product (ACP) process developed by Engineering Technology Associates, Inc. (ETA), Troy, MI. The ACP process incorporates the Heeds Professional software package from Red Cedar Technology, Inc., which allows FSV developers to automate the design-optimization process. Thus, they’re able to quickly and efficiently analyze such a wide variety of forming options. Shaw noted some 30 different materials and 19 process variations being reviewed by the FSV team, alerting attendees to a “mass paradigm shift” in the vehicles will be developed in the near future.
Three Cheers for the Ford F-150
Receiving special recognition at GDIS 2010 was Ford Motor Co.’s F-150 research and development team, which received the annual Automotive Excellence Award from the Automotive Applications Council of the Steel Market Development Institute (SMDI) honored with its. The team was recognized for its cost-effective and efficient use of advanced and ultra high-strength steel, which helped to minimize the vehicle’s weight while maintaining its durability and safety
Among the advanced high-strength steel features of the F-150 are a hydroformed front-end, low-pressure hydroformed dual-phase 780 roof rail, boron hot-stamped B-pillar reinforcement and high-strength side rails.
