Absorbed Power As an Indicator of Health Risk Associated With Whole-Body Vibration Exposure
Bibliographic record
Abstract
Abstract The human body behaves like a vibrating physical system having mass, elastic and damping properties. In order to study the biodynamic behavior of the body, it is common practice to model the body as a lumped single or a multiple-degree-of-freedom (MDOF) system. Standards have been developed using the frequency-weighted root-mean-square (rms) acceleration input to the body as the primary measure of whole-body vibration exposure. In this paper, absorbed power during exposure to vertical whole-body vibration is considered as a potential indicator of the physical stress affecting comfort and health. A four-degree-of-freedom biodynamic model is chosen to represent the body and the absorbed power for the different body segments and the total body is computed. On the basis of the model and of the guidance provided in ISO 2631-1:1997 relating vibration exposure with health risk, computations are carried out to define a health guidance caution zone based on absorbed power.

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.
