  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,...

  W pracy przedstawiono wyniki pomiaru oporu toczenia opon kolcowanych i po usunięciu kolców na nawierzchni poroelastycznej. Badania przeprowadzono na stanowisku bębnowym Katedry Pojazdów i Maszyn Roboczych Politechniki Gdańskiej. Opony kolcowane mają o około 5% wyższy współczynnik oporu toczenia w porównaniu z oponami nie kolcowanymi.

  Work Package 6 deals with environmental impacts of PERS use, including noise and rolling resistance. This report covers preliminary noise tests performed in the laboratory and at the road test sites. The obtained results indicate that PERS material reduce noise considerably - up to 12 dB in comparison to SMA16 reference surface. Noise reduction properties are especially visible in the case of factory produced PERS slabs supplied...

  - Rok 2014

  Tire rolling resistance is one of the factors related to tire/road interaction that has important influence on road vehicles performance. Raising fuel price and increased concern related to the environmental changes result in growing interest in reduction of tire rolling resistance that influences fuel consumption, especially in free-flowing highway traffic with moderate speeds. There are several methods of tire rolling resistance measurements....

  - INTERNATIONAL JOURNAL OF AUTOMOTIVE TECHNOLOGY - Rok 2018

  Temperature is a very important factor controlling rolling resistance of road vehicle tyres. There are at least three different temperatures that may be considered as important factors controlling thermal conditions of the rolling tyre. The most common measure of the thermal conditions during tyre rolling is ambient air temperature. The other two are: pavement temperature and “tyre” temperature. Tyre temperature is the most difficult...

  - Road Materials and Pavement Design - Rok 2017

  Tyre performance, one of the critical factors for vehicle users, is strongly related to theroad surface characteristics, most notably to the pavement texture. Phenomena that occur at the tyre/road interface affect tyre friction (skid resistance), rolling resistance, tyre wear and tyre/road noise. This article deals with relationship between surface texture and rolling resistance of light and heavy vehicle tyres. Mean profile depth...

  W pracy przedstawiono stanowisko bębnowe do badania oporu toczenia opon samochdowych w warunkach laboratoryjnych. Zaprezentowano także przyczepę dynamometryczną do badania oporu toczenia opon samochodowych w warunkach drogowych. Stanowisko bębnowe i przyczepa zosały zbudowane w Katedrze Pojazdów i Maszyn Roboczych Politechniki Gdańskiej. Omówiono wpływ wzdłużnego pochylenia drogi i naporu powietrza na badane koło na dokładność...

  Tire rolling resistance is one of the most important resistive forces acting on road vehicles. It depends on tire and surface characteristics as well as vehicle operating parameters. This paper deals with the influence of road surface texture on rolling resistance of passenger car tires. Results of road measurements performed on variety of road surfaces are presented.

  - MEASUREMENT - Rok 2019

  Tire rolling resistance is one of the most difficult tire parameters to measure. The reason is that for modern tires the force of rolling resistance corresponds to 0.5–1% of tire load, thus measurements of very small forces must be performed in a heavily loaded system. This constitutes great problems, especially in road conditions. Laboratory measurements are easier to perform, as the environment may be better controlled, but roadwheel...
