SEVERAL DESIGN ISSUES ON THE TUNABLE ELECTROMAGNETIC VIBRATION ABSORBER
Bibliographic record
Abstract
This paper addresses several design issues related to a newly developed electromagnetic vibration absorber (EMVA). The EMVA consists of a clamped-clamped aluminum beam and a permanent magnet that is embedded in the centre of the beam and placed between two poles of a C-shaped electromagnet. By varying the current of the electromagnet, stiffness of the EMVA can be adjusted instantaneously. The EMVA is capable of suppressing vibration of the primary system excited by a harmonic force with a variable frequency. First a simplified equation is proposed to compute the flux density distribution in the gap of the electromagnet. The approximation error caused by the simplification is investigated. Second, the effect of cross-sectional shapes of the permanent magnet on the variable magnetic stiffness and the constant magnetic stiffness is examined. Finally, the effect of the gap spaces of the electromagnet on the variable magnetic stiffness is studied.

How this classification was reachedexpand
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.
