A non-linear dynamic approach to the motion of four-wheel-steering vehicles under various operation conditions
Bibliographic record
Abstract
This research aims to analyse systematically the non-linear dynamic behaviour of four-wheel-steering (4WS) vehicles. A practical non-linear dynamic model of multiple degrees of freedom for 4WS vehicles is established. The non-linear model presented is shown to be feasible for the vehicles under normal and the other operation manoeuvres. Compared with those of documented investigations, this model may be employed to analyse the motions of the vehicle and motions of the vehicle wheels in turning and braking processes together with the consideration of the effects of air drag and wind. Numerical simulation for the motion of the 4WS vehicles under various operation manoeuvres is performed with the model established. Comparison of the behaviours of 4WS and two-wheel-steering vehicles is also presented with respect to the inputs on the steering system, the manoeuvrability, the stability, and the relationship between the steering phase and vehicle speed.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
