Dynamic platform
The dynamic platform (also called dynamic area, driving-dynamics area) is a special, contiguous, large-surface, asphalt-paved element of vehicle industry test tracks, which enables the performing of high-speed vehicle dynamics tests under dynamic extremes and safe circumstances.[1][2]
Structure and Characteristics
The central element of the dynamic platform (generally a disc) enables the unrestricted configuration of test cases, the routes and borders of which can be marked out quickly, flexibly, and safely with the help of either buoys or other marking methods. The angle of depression of the platform is low; consequently, the layout of the track enables testing on wet surfaces as well. For performing high-speed test cases, it is necessary to construct connected acceleration lanes with an appropriate length, which enable the required amount of accelerating for heavy-duty combination vehicles. The acceleration lanes, depending on the layout of the dynamic platform, are connected to the disc at various angles. In order to perform repeated tests, it is necessary to design a route separated from the test (braking) zone that allows the test vehicle to return to the beginning of the test lane quickly and safely. Run-off areas paved with gravel are provided around the disc for safety reasons.[1][2]
Goal and Utilization
The dynamic platform is suitable for conducting various kinds of test cases, e.g., testing dynamic effects related to high-speed advancement in narrow curves or high-speed tests requiring ESP and ABS activity (braking maneuvers, double lane changing, J-turns, circular or slalom driving tests).
Dynamic Platforms of Existing Test Tracks
Currently, most test tracks in Europe feature dynamic platforms. The most well-known examples are the Boxberg Proving Ground (constructed by Bosch, Germany), Automotive Testing Papenburg GmbH (constructed by Daimler, Germany), Applus Idiada (Spain), Aldenhoven Testing Center (Germany), and AstaZero (Sweden). A test track also suitable for testing self-driving vehicles and automated operation is currently under construction in Hungary, which will also feature a dynamic platform.
Boxberg Proving Ground, Boxberg, Germany[3]
The dynamic platform of the Boxberg Proving Ground is a circular surface 300 m in diameter and partially wettable. Two acceleration lanes have been added to it, one of these partially shared with the acceleration lane of the braking platform.
Automotive Testing Papenburg GmbH, Papenburg, Germany[4]
The most extensive part of the dynamic platform at the Papenburg test track has an overall size of a circular surface 300 m in diameter. The trapezium-shaped area is 570 m long and 15 to 100 m wide. There are two further tangential acceleration lanes, 8.5 m wide and 640 m long, whereas the length of the middle section suitable for acceleration is 800 m.
Aldenhoven Testing Center, Aldenhoven, Germany[5]
The dynamic platform of the Aldenhoven Testing Center is circular in shape and has a diameter of 210 m; the acceleration lane is 400 m long and may be extended to 500 m when choosing a different starting point.
AstaZero, Sweden, Hällered[6]
The dynamic platform of AstaZero is 240 m in diameter, and its acceleration lane is 1 km long. It also has a car park equipped with a charging network for electric vehicles.
Applus Idiada, Spain, Tarragona[7]
The overall size of the circular section of the dynamic platform at the Idiada test track is 300 m × 300 m, and the trapezium-shaped section in the middle is 400 m × 15–100 m. It also has three connecting lanes, all 2 × 4 m wide; the middle lane is 300 m long, and the tangential ones are 450 m long.
Zala ZONE Vehicle Industry Test Track, Zalaegerszeg, Hungary[8]
In the first phase of constructing the test track near Zalaegerszeg, the dynamic platform disc (300 m in diameter) and a 740 m long western acceleration lane will be completed. The platform will be suitable for conducting both passenger and heavy-duty vehicle tests. The eastern acceleration lane, to be completed in the second phase, will feature an extensive basalt-paved surface suitable for conducting drive stability and running-gear tests on low-grip pavement. The disc and the basalt surface will be built with a wetting system, enabling testing under the most unfavourable wet friction conditions.
