Pod dejstvom pobuda od mikroneravnina puteva, pogonske grupe, kao i od uslova kretanja (ubrzavanje, kočenje, krivolinijsko kretanje) mase teretnih vozila vrše složena prostorna oscilatorna kretanja. Negativan uticaj tih kretanja, odnosno dinamičkih opterećenja koje ona izazivaju i prenose na noseći sistem vozila, može se smanjiti pravilnim izborom položaja i karakteristika oslonaca pogonske grupe. Za analizu tih uticaja se mogu koristiti teorijske, eksperimentalne i kombinovane metode. U ovom

Pri tome su posmatrane vibracije pogonske grupe jednog teretnog motornog vozila srednje klase iz proizvodnog programa FAP.

In this article, the research was carried out with use of the theoretical methods by using simplified mechanical model of the powertrain, wherein the observed vibration of the truck produced in FAP.
