Its design is described and some experimental results are given. These results confirm that in order to describe friction force in contact between the car tire and the road it is essential to use a dynamic friction model. Moreover, they indicate that the existing dynamic friction models might be physically incorrect in regards to the change of friction coefficient for an asperity bristle passing through the contact surfaceZ namenom boljšega razumevanja dinamičnega obnašanja torne sile na stični površini med avtomobilsko pnevmatiko in cesto je bil razvit laboratorijski model za eksperimentalne raziskave drsnega para guma - asfalt. V članku je predstavljena zasnova modela in nekaj rezultatov eksperimenta. Rezultati potrjujejo, da je za opis torne sile na stiku med avtomobilsko pnevmatiko in cesto nujna uporaba dinamičnega modela trenja. Poleg tega nakazujejo, da so obstoječi dinamični modeli trenja morda fizikalno neustrezni z vidika spremembe koeficienta trenja med prehodom asperita prek stične površineTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
