BWR Motorsports GmbH has developed cutting-edge technology which enables crucial tire Dynamic Mechanical Analysis (DMA) testing to take place at the racetrack.
The portable tire testing unit – MOTITE – provides the ideal solution for race teams across series such as Formula One and WEC to measure tire grip levels and rank the tires on track. The software allows an immediate grip level output and enables measurement and analysis to be carried out directly on the tire. Its small size and light weight, means it is easy to handle and transport – essential for the demands of a global race series.
Erich Baumgärtner, BWR Motorsports GmbH, said: “With tires playing such an essential role in motorsport, efficient and quick analysis is very important as production and storage cause substantial tolerances within a batch of tires. However, previous technology available was difficult to use on the racetrack as it requires stationary conditions and a material sample, which needs to be cut out of the tire. The portability and ease of use of the MOTITE technology enables racing teams to measure all sets of tires after allocation in under an hour, allowing them to easily rank the tires available.”
MOTITE covers sinusoidal strain applied on the tread and computation of shear modulus and loss coefficient. It also measures tread temperature, wheel weight and tire diameter to give teams a full analysis of the tire.
The unit features a rotary motor measure head torque sensor, linear drive to apply preload and load cells to measure wheel weight. It also has a touch screen display to increase ease of use.
The first delivery to a Formula One team took place in 2021.
