Study of instability mechanisms of trucks turning right at long downhill T-junctions based on Trucksim simulation.

ABSTRACT: The aim of this study was to investigate the influence of road factors on the safety speed threshold of a lorry turning right around a corner at a the bottom of a long downhill T-junction. Trucksim simulation software was chosen to construct a model for investigating the turning instability mechanism. A three-axle truck was chosen as the simulation vehicle and road adhesion coefficients of 0.2-0.75, road super-elevations of -2-8%, turning radii of 20-100 m, and vehicle overcharge of 0-100% selected for tuning. Simulation experiments were carried out for different bending conditions, investigating the effects of each influencing factor on the destabilization speed threshold using the control variable method. The vehicle's lateral load transfer rate and lateral acceleration were indicators f
