Abstract
This paper investigates the dynamic response of an aircraft seat structure. The study involved the use of a finite element software to predict aircraft seat vibrations during takeoff-like flight conditions. The described model is validated by performing experimental dynamic response measurements of an aircraft seat subjected to actual take off excitation recordings obtained onboard an aircraft. The accuracy of the model is investigated by comparing the simulated properties with experimental modal analysis and seat plate dynamics data. Moreover, the severity of the transmitted vibrations to the seat surface is assessed using the seat effective amplitude transmissibility (SEAT) method. Results show that the numerical model is able to replicate the dynamic and modal properties of the aircraft seat. The numerical and experimental SEAT values computed through different methods were also found to be in good agreement. This developed model can be used to predict and improve the dynamic comfort of aircraft seats.

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 it
