With automotive engines it is now common to join a large number of belt-drives into a single, long belt-drive with several tensioner pulleys. However, these belt-drives can exhibit complex dynamic behaviors; therefore it is very important to predict the dynamics response of such systems using validated numerical models. The aim of this paper is to perform the validation of a developed belt-drive model. The validation of this belt-drive model was performed using a two-pulley belt-drive. The numerically obtained results are compared with experimental data under various operational conditions. Finally, the applicability of the belt-drive model is presented by simulating a serpentine belt-drive, considering non-steady, belt-drive operational conditionsZaradi vse večje zanesljivosti jermenskih gonil se je njihova uporaba v zadnjih nekaj desetletjih zelo razširila. Po zaslugi nizkih stroškov inštalacije in vzdrževanja, možnosti blaženja šokov in dobrih obratovalnih karakteristik že vrsto let nadomeščajo verižna in zobniška gonila kjerkoli je to mogoče. Zlasti v avtomobilski industriji, ki predstavlja velik dele tržnega gospodarstva, je v zadnjem času značilno, da se več jermenskih gonil združuje v eno samo daljše jermensko gonilo. Ta jermenska gonila izkazujejo kompleksno dinamsko obnašanje, zaradi česar je potrebno okarakterizirati dinamski odziv tovrstnih sistemov z uporabo validiranih numeričnih modelov. Na osnovi teh modelov lahko določimo optimalne obratovalne, oblikovne in materialne parametre gonilaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
