Investigation of the 3-D vibration transmissibility on the human hand-arm system using a 3-D scanning laser vibrometer
Bibliographic record
Abstract
The vibration transmissibility on the human hand-arm system subjected to vibrations in three orthogonal directions was investigated. Seven healthy male subjects participated in the study and the experiment was carried out on a novel 3-D vibration test system. The vibration controller was programmed to generate broadband random vibration in the frequency range of 16-500 Hz along each direction. The measured tri-axial transmissibility functions are found to vary among the subjects and their basic distributions of the transmitted vibration on the hand-arm system are similar. The magnitudes of the tri-axial transmissibility measured at six important locations on the hand-arm system of the subject show that transmissibility is a function of frequency. which varied greatly with measurement location and vibration direction. The resonances observed at the wrist, elbow, and shoulder are consistent with the first resonance observed in the driving-point biodynamic response in each corresponding direction.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
