This paper investigates the influence of load distribution on the dynamic stability of a tractor-semitrailer during turning maneuvers for three load distribution cases (forward, uniform, and backward) across various forward velocities with a constant steering angle. Key findings reveal that for lateral slip conditions, the maximum permissible velocity is lowest with forward load placement, followed by uniform distribution, and highest with backward placement. This indicates that backward load placement allows the vehicle to corner at higher speeds. Analysis of yaw velocity gain, lateral acceleration gain, and articulation angle gain responses shows that forward load placement leads to earlier and more pronounced oversteer behavior in both the tractor and semitrailer as velocity increases, compared to uniform distribution. Conversely, backward load placement results in significantly less pronounced oversteer and provides the best stable state during cornering. In conclusion, load distribution significantly impacts the dynamic stability of tractor-semitrailers in turns, with backward load placement providing superior stability by reducing oversteer and jackknifing tendencies.
