Abstract
To investigate the lateral stability of an articulated steer vehicle with a rear-mounted load, a linearised model of a forestry skidder carrying a log is devised. In this model, a torsional spring and damper are used to represent the stiffness and damping in the hydraulic cylinders at the articulation joint. The results show that when the vehicle is carrying a rear-mounted load, the oscillatory instability or snaking may occur at lower vehicle speeds. However, when the torsional spring stiffness or damping at the articulation angle is increased to an appropriate value, the snaking can be removed or delayed to higher speeds. To verify the results from the analysis of the linearised model, the motion of a virtual prototype of the vehicle is simulated in ADAMS/View. The results from the simulations and linear stability analysis are consistent.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
