A Comprehensive Study of the Impact of Tread Design on the Tire-Terrain Interaction using Advanced Computational Techniques
Bibliographic record
Abstract
<div class="section abstract"><div class="htmlview paragraph">This paper investigates the impact of tread design on the tire-terrain interaction of two similar-sized truck tires with distinctly different tread designs running over various terrains and operating conditions using advanced computation techniques. The two truck tires used in the research are off-road tires sized 315/80R22.5 wide which were designed through Finite Element Analysis (FEA). The truck tire models were validated in static and dynamic domains using several simulation tests and measured data. The terrain includes a flooded surface and a snowed surface which were modelled using Smoothed-Particle Hydrodynamics (SPH) technique and calibrated using pressure-sinkage and direct shear tests. Both truck tire models were subjected to rolling resistance and cornering tests over the various flooded surface and snowed surface terrain conditions on the PAM-CRASH software. Other tire operating conditions included varying vertical loads, terrain depths, longitudinal speeds, and slip angles. The flooded surface depth was set up at 0%, 10%, and 25% sidewall height, and the snowed surface depth was set up at 10%, 35%, and 50% sidewall height. The truck tires were subjected to vertical loading of 13 kN, 27 kN, and 40 kN, longitudinal speeds of 10 km/h, 50 km/h, and 100 km/h, and slip angles of 2 degrees, 6 degrees, and 12 degrees. To study the impact of the different tread designs between the two similar-sized tires, the Rolling Resistance Coefficient (RRC), lateral force, self-aligning moment, and overturning moment were determined for both tires and compared.</div></div>

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.
