ANALYTICAL INVESTIGATIONS OF THE GRAVITY EFFECT ON THE DYNAMICS AND PERFORMANCE OF CENTRIFUGAL PENDULUM VIBRATION ABSORBER
Bibliographic record
Abstract
Centrifugal Pendulum Vibration Absorber (CPVA) has been effectively used inrotating and reciprocating machines to control torsional vibrations passively. Thisresearch presents results from analytical investigation of rotor systems integratedwith CPVA. The system under investigation is modeled as a rotating disk attachedwith CPVA in which the disk is subjected to an external simple harmonic torque.Mathematical model of a rotor fitted with a CPVA has been formulated and theequations of motion are derived using Lagrange principle. The effect of gravity due toCPVA operating in a vertical plane with a horizontal shaft has been considered in theformulation. The results are also compared with those based on CPVA operating in ahorizontal plane in which the effect of gravity has been neglected. Moreover,softening nonlinear behavior of the pendulum and its effect on the natural frequencyof the system has been investigated.

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.
