Abstract
Vibrations in rotating shafts have been studied because of their great importance in engineering applications and ways to reduce these vibrations using modern techniques such as magnetic bearings and traditional bearings.A representative model of magnetic bearings was built using COMSOL program, and the effect of adding these bearings on amplitude, vibration reduction, and frequency behavior was calculated. When active magnetic bearings were added to the rotating systems, the level of vibrations was greatly reduced to about 60%, giving them a more stable and firm character. The changes that occur to the vibrations in the rotating shafts when changing the coil current and the distance of air gap in magnetic bearings, as well as the effect of a change in the amplitude of forces entering magnetic bearings on the value of the natural frequencies in magnetic bearings, were also monitored.Using SigView software, the Fast Fourier Transform (FFT) was employed to evaluate system vibrations and detect the frequency domain of the system supported by active magnetic bearings.

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
