TOKYO, April 11, 2007 - Kobe Steel, Ltd. and voestalpine Automotive, Inc.
will receive the 2006 SAE/AISI Sydney H. Melbourne Award for Excellence in the
Advancement of Automotive Steel Sheet for a technical paper submitted to the
SAE. The authors of the paper will be presented the award at a ceremony
on April 17 during the 2007 SAE World Congress in Detroit, Michigan.
The
recipients are Kenichi Watanabe and Mie Tachibana, researchers at Kobe Steel,
and Marcus Wiemann and Dieter Frankenburg of voestalpine Automotive. The award-winning
paper is titled "Vehicle Side Structure Concept using Ultra High Strength
Steel Sheet and Rollforming Technology" (SAE Paper No. 2006-01-1403).
Ultra
high strength steel (UHSS) sheet, with tensile strengths of 1,180MPa to 1,470MPa,
is generally difficult to press form. Over a three-year period, Kobe Steel
and voestalpine Automotive conducted research on rollforming UHSS sheet into
parts for a new side structure concept to reduce vehicle weight. The steel
sheet was rollformed into such parts as the pillars, roof cross member, floor
cross member, and side sills.
Rollforming is an operation by which steel
strip is passed through rolls that gradually bend the sheet into a cross-section
form. This process is commonly used in making round pipe, a construction
material.
The new side structure concept satisfied IIHS (Insurance
Institute for Highway Safety) side impact test criteria. In addition,
the weight of the side structure module was reduced by roughly 25%, a savings
of 14.4 kg, in comparison to the same structure made of stamped parts in the
reference vehicle. This concept could promote the application of automotive
structural parts made of rollformed cross-sections.
Established in 1997,
the SAE/AISI Sydney H. Melbourne Award for Excellence in the Advancement of
Automotive Steel Sheet recognizes authors who effectively demonstrate ways of
further utilizing steel sheet in automobiles. The award honors the late
Sydney H. Melbourne, a director of market development and product application
at Dofasco, Inc. Melbourne is widely recognized for his contributions
to the steel and automotive industries.
The SAE World Congress is the
top technical program in the world for automotive engineering interests. The
Kobe Steel-voestalpine technical paper was chosen from over 1, 200 technical
presentations at the 2006 SAE World Congress. This is the first time in eight
years that employees of a Japanese company have been selected for this award.
