STUDY OF ROLLING RESISTANCE MECHANISM

Mariana ARGHIR, Adrian Ilie Virgil LEU

Abstract


The rolling mechanism is a part of the auto tire, which are the authors conducted over the several years. The underlying idea in most of the  programs was to replicate real-life conditions in order to better  understand tire behaviour while using the advantage of quasi-controlled conditions. This paper is made because the number of vehicle in use is increasing every year and more vehicles are consuming more fuel. Vehicle manufacturers are making great efforts to develop fuel efficient engines and vehicle designs. In United States, light-duty vehicles (cars & light trucks) are responsible for about 20% of the nitrogen oxides,
27% of the volatile organic compounds, 51% of the carbon monoxide, and roughly 30% of all the carbon dioxide (the main greenhouse gas) emitted from human activities. When a tire rolls on the road, mechanical
energy is converted to heat as a result of the phenomenon referred to as rolling resistance. Effectively, the tire consumes a portion of the power transmitted to the wheels, thus leaving less energy available for
moving the vehicle forward. Rolling resistance therefore plays an  important part in increasing vehicle fuel consumption.
