Abstract
<div class="htmlview paragraph">This paper addresses modeling and system identification of a McPherson strut quarter-car suspension. Constrained equations of motion in the Lagrange multiplier form are used to characterize the dynamic behavior of both a linear and a non-linear McPherson strut quarter-car suspension model. A Hilber-Hughes-Taylor integrator is used to simulate the suspension's response to a displacement input. The simulated response of both models is compared to the experimental response recorded from a quarter-car test rig equipped with a McPherson strut suspension, for system identification purposes. The performance of both models is discussed in the context of the basic linearity of the experimental suspension.</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 it
