Experimental and Analytical Evaluations of a Torsio-Elastic Suspension for Off-Road Vehicles
Bibliographic record
Abstract
<div class="section abstract"><div class="htmlview paragraph"> The ride performance potentials of a prototype torsio-elastic axle suspension for an off-road vehicle were investigated analytically and experimentally. A forestry vehicle was fitted with the prototype suspension at its rear axle to assess its ride performance benefits. Field measurements of ride vibration along the vertical, lateral, fore-aft, roll and pitch axes were performed for the suspended and an unsuspended vehicle, while traversing a forestry terrain. The measured vibration responses of both vehicles were evaluated in terms of unweighted and frequency-weighted rms accelerations and the acceleration spectra, and compared to assess the potential performance benefits of the proposed suspension. The results revealed that the proposed suspension could yield significant reductions in the vibration magnitudes transmitted to the operator's station. The field evaluations revealed that suspended vehicle could yield 35%, 43% and 57% lower frequency-weighted rms accelerations in the <i>x</i> -, <i>y</i> - and <i>z</i> -axis, respectively, compared to the unsuspended vehicle, when loaded. A 13-degrees-of-freedom model of the suspended vehicle was subsequently developed and validated using the measured data, which could serve as a design tool for deriving optimal suspension designs for a wide range of vehicles. The model results revealed reasonably good agreements with the measured vibration spectra. From the simulation results, it was further concluded that a reduction in the vertical stiffness of the torsio-elastic member would yield beneficial effects on the overall weighted vertical and pitch rms acceleration magnitudes. </div></div>

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.
