Automotive Giant, General Motors, recently opened its new reduced scale wind tunnel at its Technical Center in Michigan. The $30M testing facility allows GM to test reduced-sized vehicles on a simulated road to accelerate and verify fuel-saving designs in the vehicle development process. With 35,000 square feet to use, GM can aerodynamically test clay models up to 40% of the scale of a full sized vehicle, and is equipped with a conveyor-style rolling road system that simulates real-world highway driving conditions up to 155mph.
Testing reduced-sized vehicles on a simulated road enables engineers to reduce wind drag in a full-size vehicle design. It is located next to GM’s full-scale wind tunnel that has been in operation since 1980 and which will be upgraded next year with its own full-scale rolling road system and other improvements.
More often than not, load cells are employed in such high tech wind tunnels to measure the force of wind on the design. Interface provides a wide range of load cell and torque sensor automotive applications. For more information visit our Automotive Applications page.
