Abstract
Abstract This contribution discusses the non‐linear dynamic behaviour of a rotor system equipped with a compliant seal. The investigated model consists of a Laval ‐Rotor and a stiff seal ring which is visco‐elastically supported. The fluid forces stemming from the turbulent incompressible lubricant film are accounted for by the non‐linear Muszynska model. The added compliance leads to an improved stability behaviour of the steady state. Within the post‐critical regime the additional compliance gives rise to bifurcations of the stationary vibration: Hopf bifurcations lead to limit cycles which can loose their stability via Neimark‐Sacker bifurcations.

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
