Accurate rolling resistance Rolling resistance measurements can be influenced by a number of factors
Abstrakt
Tire rolling resistance is one of the most difficult-to-measure parameters of the tire/ pavement interface, especially if road measurements are required. First of all, it is necessary to measure a fairly small force in the system that is heavily loaded by other forces and subjected to many adverse effects causing measurement errors. The second problem is related to the fact that tire rolling resistance depends on many factors, such as temperature, which are difficult to control outside the laboratory. The Technical University of Gdańsk (TUG) performs tire rolling resistance measurements both in the laboratory using the drum method and on the road using the R2 Mk.2 test trailer. Typical laboratory measurements (for example, measurements performed according to ISO standards) are executed on smooth steel drums or on drums covered with Safety Walk material, which has a very fine texture. This is the most important drawback of the drum method as deflections of the tread elements are very different on smooth steel than they are on typical, ‘real’ road surfaces such as SMA or PCC. On top of this, the curvature of the drum makes the footprint of the tire and deflection of its elements very different from that on a typical flat road.
