Dynamic characteristics of a ball bearing-offset disk rotor system with whirling-swing coupling
Bibliographic record
Abstract
Dynamic model of a ball bearing-offset disk rotor system with whirling-swing coupled vibration was built considering rotor disk offsetes and disk swing vibration.In the model of ball bearings,clearance of bearings,nonlinear Hertzian contact force between balls and races and varying compliance vibration were considered.Numerical methods were adopted to solve and compare the dynamic responses of the system under different disk offsetes with or without disk swing vibration considered.Effects of bearing clearance variation on the dynamic performance of the model under different rotor disk offsetes were analyzed.It was shown that the nonlinear dynamic response features of the offset disk rotor system are enhanced obviously considering rotor disk swing vibration; the system under different rotor disk offsetes contains diverse frequency components at the same speed; the larger the level of rotor disk offset,the higher the sensitivity of the critical speeds of the system to bearing clearance variation.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
