Abstract (Croatian)

Vozila s prikolicom danas su čest sudionik u prometu te je stoga važno osigurati sigurno i efikasno sudjelovanje u prometu takvog vozila. Jedan od značajnih pobudnih faktora na stabilnost same prikolice jest bočna pobuda na prikolicu. Izvor bočne pobude može biti npr. bočni udar vjetra, djelovanje centrifugalne sile u vožnji zavojem, zakret volana, poprečni nagib podloge i sl. Ona uzrokuje smetnje u stabilnosti kako prikolice tako i vučnog vozila te može dovesti do gubitka stabilnosti prikolice i vozila. Ovim radom, korištenjem simulacija i teorijski potkrijepljenim podacima prikazani su utjecajni faktori na stabilnost vozila tijekom bočne pobude. Prikazani su najutjecajniji parametri koji utječu na stabilnost vozila, a naglasak je bio na parametrima prikolice. Utjecaj parametara analiziran je u nekoliko karakterističnih ispitnih procedura kojima se u stvarnim uvjetima ispituju takva vozila, a koje su definirane na temelju literature i pravilnika.

Abstract

Today it is often to see vehicle towing a trailer, and because of that it is important to ensure safe and efficient participation in the traffic of such a vehicle combination. One of the major impacts on the stability of the trailer itself is the lateral thrust of the trailer. The cause of the lateral thrust may be, for example, the side impact of the wind, the action of the centrifugal force while driving thrue corners, the steering wheel rotation, the transverse inclination of the road, etc. It causes disturbance in stability of trailer and towing vehicle, and can lead to loss of stability of the trailer and the towing vehicle. Using simulations and theoretically substantiated data, factors influencing vehicle stability, during the lateral boost, are shown in this thesis. The most influential parameters that affect the stability of the towing vehicle and trailer are presented, with accent on the parameters of the trailer. With the help of literature, there is described real life procedures witch are used for vehicle testing in such conditions.
