TRIALS have started on the wind tunnels at the Shanghai Ground Transport Wind Tunnel Center in Jiading District.
The center's aerodynamic-forces aero-acoustic wind tunnel is undergoing tests, while the thermal wind tunnel will be tried out in a month.
As China's only public testing platform and one packed with almost all testing functions, the center provides a testing infrastructure for cars, high-speed trains, motorcycles and aeroplanes.
It will have a major influence on the development of the auto industry in the district and the cohesion of the talents from other districts.
Yang Zhigang, a professor from Tongji University's automobile college, said the aerodynamic-forces aero-acoustic wind tunnel will mostly be used to test new types of cars that will go on to the market three to four years later. Tests include wind resistance, yawp levels inside and outside cars and windshield wipers.
The thermal wind tunnel is targeted at new types of cars which will be on the market within 12 to 18 months. It can test automobiles' performances, air conditioning and cooling systems.
A variety of vehicles - cars, sports utility vehicles, minibus and light trucks - can be placed in the wind tunnels. The tests will help to find the best and safest lines and the most durable parts for the vehicles.
Currently, more than 100 types of vehicles are developed each year domestically. In the past, it has cost a lot for domestic auto businesses to transport their products to Europe or Russia for wind tunnel tests. This not only extends the development cycle, but also reduces the safety of the technical data.
After the technology is localized, businesses will be able to reduce costs by 15 percent.
The design of the wind tunnels at the center has so far surpassed normal requirements. Usually a required wind speed for an auto test is 80 kilometers per hour. But at the aerodynamic-forces aero-acoustic wind tunnel, the wind speed can reach up to 250 kilometers per hour, which satisfies requirements for testing high-speed trains, racing cars and aircraft for civilian use.
The total cost of setting up the center reached 490 million yuan (US$ 71.79 million). As well as money from the central government and the Shanghai government, 100 million yuan was raised from more than 10 businesses to cover the trials.
Jiading District has become an "auto city," with its wind tunnel center, a vehicle inspection and examination center, a test-drive center and a new energy center.
