CHONGQING, China (July 22, 2016) — The China Automotive Engineering Research Institute (CAERI) in Chongqing has ordered a Flat-Trac Rolling Road System from MTS Systems Corp. to be used in CAERI's aero-acoustics wind tunnel laboratory.
By using the Flat-Trac system in conjunction with the wind tunnel, CAERI technicians will be able to measure air flow between the vehicle and road surface, along with the effect of rotating wheels on their aerodynamic profiles, thereby making the simulation as realistic as possible, MTS said.
“Concerns about the environment mean that automobile manufacturers need to improve the fuel economy of their models,” said Wang Yong, director of Automotive Wind Tunnel Center of CAERI.
Flat-Trac systems apply forces and motions to a tire running on a continuous flat belt, MTS said, allowing the user to gain insight into how a specific tire design affects vehicle dynamics by measuring tire force and moment.
“Combining MTS Flat-Trac Rolling Road technology with our wind tunnel resources will enable us to accurately capture and analyze data relating to a multitude of different test parameters,” he added. “From this, aerodynamic and structural design improvements will be possible that allow significant energy savings without compromising vehicle performance.”
