In the era of electromobility and growing efficiency standards, tire testing technology must keep up with increased expectations of safety, range and precision in the design of vehicle components. The key innovation supporting the development of new generation tires is the High-Speed Tirescan ™ -Texcan system enabling dynamic and repetitive measurements of pressure and pressure tire in motion , even at speeds up to 265 km/h.
Breaking of restrictions on traditional methods
Previous methods, such as road tests, mascara, analysis on glass plates or drum tests, have numerous disadvantages: they are unique, do not reflect dynamic conditions, and the contact charts can be distorted by the elements of the research track (e.g. the curved drum surface). What's more, they do not include dynamic centrifugal forces, slip angle or acceleration/braking.
High-Speed Tirescan ™ has been developed to eliminate these barriers. It is based on tests conducted in fully controlled conditions - on a flat track, where each variable (load, tilt, temperature) can be thoroughly set and changed in a repeatable manner.
System components: Precision technology in practice
A thin piezorezstance sensor
Only 0.2 mm thick, made of flexible bending and abrasion -resistant materials. It can be mounted even under sandpaper, thanks to which the actual friction coefficient is preserved. Measurement of cross -sectional pressure with a range of 10 to 600 PSI (69–4137 KPA) gives it universality - from motorcycles, through passenger cars, to truck tires.
One sensor withstands thousands of tests and shear forces up to 15 kN, e.g. during sharp turns with large overloads.
Wireless electronics Tekdaq 210
The compact device recording data from the matrix 128 sensors with a frequency of up to 20 kHz, provides capturing every millimeter of the changing tire contact surface. The system works independently, allows data transmission wirelessly or using the SD card, and its battery allows 3 hours of continuous operation - ideal for intensive test campaigns.
Integrated TexCan software
The user can introduce a test plan, observe changes in pressure distribution during the test, compare many results or generate an average profile for a given tread. The system automatically adjusts the surface reproduction depending on the speed, creating a reliable "footprint" - a dynamic contact image.
key asset: dynamic understanding of the tire's behavior
Thanks to Tirescan ™ technology, engineers can in real time analizować, jak zachowuje się opona w odpowiedzi na:
- Vertical load : reveals how the contact surface is expanding and when the tire fully adheres to the surface - which allows you to identify excessive load.
- slip speed and angle : shows how the tire shape changes - e.g. at speeds above 100 km/h, the shoulder length can increase by over 20%. A change of pressure is also recorded, especially in the middle of the tire forehead.
- Extreme maneuvers : During high overloads tests, a unique phenomenon was registered. pressure gap, potwierdzone również obrazowaniem termowizyjnym. Siły boczne powodowały wyboczenie pakietu pasów, prowadząc chwilowo do braku styku części bieżnika z drogą. Zjawisko to zweryfikowało teoretyczne modele zachowania opony.
