Abstract
This research intends to analyze the dynamic stability of a nonlinear cracked rotor system with unsymmetrical viscoelastic supports. Nonlinear governing equations for the cracked rotor system subjected to periodic forces generated in machining are established. The linear and nonlinear dynamic stabilities of the system are investigated on the basis of the HBM method, utilizing Lyapunov theory and the Floquet criterion. The effects of the masses of shaft and disk together with the nonlinearity of the rotating system on the behavior of the system are all taken into consideration. Numerical simulations of the system are also performed. The influences of various factors on the principal regions of instability are studied. The results obtained in the research are compared with those found in the literature.

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
