The NTRC began operating the world’s premier force-and-moment tire test machine in January 2013 and has since become the epicenter for tire testing and tire model data fidelity. The center specializes in testing designed to complement activities performed by global tire and vehicle manufacturers. The NTRC uses transformational technology to extend tire-testing capabilities up to 200 mph, providing dynamic response and braking/torque capabilities through the entire speed range under both dry and wet surface conditions.
The National Tire Research Center (NTRC), which serves as the tire characterization division of the Global Center for Automotive Performance Simulation (GCAPS), has established itself as the premier location for passenger, light truck, and motorsports tire testing. The high-quality standards, innovative research, and unique equipment available at NTRC allow its staff to produce tire data for both objective comparisons and for the creation of such tire models as FTire and MF-Swift. The testing and modeling support conducted daily at NTRC has proven invaluable to many original equipment manufacturers (OEMs) and motorsports teams that routinely win accolades and are podium finishers.
NTRC is now expanding its testing capabilities to include outdoor surfaces and vehicle measurements. Working with a tire OEM, NTRC recently conducted measurements of seven different tire constructions on 14 different road surfaces, all in a span of two days. This outdoor testing was conducted on the Virginia Smart Road, a 2.2-mile, two-lane closed test track located in Blacksburg, Va., at the Virginia Tech Transportation Institute (VTTI). The test bed features 14 different roadway constructions that represent the majority of U.S. roadways. In-cabin noise measurements were taken across these surfaces at three different speeds and two directions of the road, with three samples collected from each speed and direction. The three samples were then averaged and reduced to include overall db(A) and a frequency analysis for each tire construction on each road surface, providing the tire OEM with an array of comparisons. Overall, these comparisons showed that different tread patterns were louder on certain roadway construction than others and that single surface measurements could be misleading to tire designers.
GCAPS is an affiliated company of VTTI, which is the largest university-level transportation institute in the country and is dedicated to advancing transportation through innovation. For more information about GCAPS, visit www.gcaps.net.
VDIL is capable of transforming the high-fidelity data generated by the NTRC into tire models that can be used for handling, ride, and load simulations. Available tire models include MF-Tyre TM’ MF-SwiftTM,and FTire’TM PAC 2002 TM CD Tire TM
Through processes developed by both VDIL and NTRC a high-quality tire model is produced in just a short amount of time at a reasonable cost.
