Abstract
<div class="htmlview paragraph">This paper presents a unified framework for addressing NVH related issues attributed to tire uniformity and Brake rotor DTV. While the focus is on the perceptible manifestation of such vibration (nibble), the presentation goes to the root-cause of nibble and how various suspension/tire/brake components contribute to the generation/amplification of such vibration. While the tire/brake excitation mechanisms have different origins, they cause the same (nibble) symptom to the driver. Results are presented for three types of vehicle suspensions, along with procedures that were developed specifically for this study and some of the understanding that was gained.. Also presented is an efficient data reduction scheme that makes it easy to visualize 3D motions of suspension components and investigate their dynamics. Amongst the “take-aways” from this study are 1) an understanding of how tire/brake excitation causes nibble, 2) an overview of the various parameters influencing nibble sensitivity, and 3) How this information can be used to alter the NVH attributes of a given vehicle.</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
