Sažetak
Car-trailer combinations are relatively popular in many countries. A trailer is a means of transport that increases the load-carrying capacity of a car. However, coupling a trailer to a car significantly affects the dynamic behaviour of the resulting car–trailer combination. The longitudinal position of the load on the trailer superstructure represents one of the key factors influencing its driving characteristics. The goal of this research is to assess the driving properties of a car-trailer combination from the perspective of driving safety. The analysis was carried out using computer simulations in a commercial multibody system software environment. Driving safety is assessed for a scenario in which the car-trailer combination passes over a road obstacle at various vehicle speeds. This approach allows the identification of load positions at which the combination becomes unstable, potentially leading to an accident. Two load levels were considered, corresponding to 20% and 80% of the trailer’s maximum load capacity. For each load case, three longitudinal positions of the centre of gravity were analysed: in front of the first axle, between the axles, and behind the second axle of the trailer. The results show that the lowest level of driving safety occurs when the car–trailer combination passes over the obstacle at high speed with the load positioned behind the second axle of the trailer. Based on the obtained results, a suitable load position ensuring improved stability and driving safety is proposed.
