For the new wind tunnel efficiency center at Volkswagen in Wolfsburg, EEW-PROTEC has developed, manufactured and installed a traverse system for positioning the carbon fiber sensors. The dimensions are approx. 12m x 9m x 3,75m.
Probably unique is the possibility to fold the complete Z-system of the truss into a horizontal position, e.g. for acoustic measurements.
Including an aerodynamically designed mandrel made out of carbon fiber, based on a design by the German aerodynamic designer Dr. Bergmann.
Siemens control system (Type 840D) with an interface to the control panel of the wind tunnel, prepared for a fully automatic measuring process based on the 3D shape of Volkswagen vehicles.
Installation and commissioning of the Traverse system in cooperation with Siemens for the commissioning of the control system which is capable of achieving a unique precision and repeatability, despite the gusts of wind over 250 km/hour.
