Resposta de sistemas dinamicos e rotores interagindo com o solo
Bibliographic record
Abstract
The present work describes the dynamic response of a system consisting of a rotor, a rigid foundation and a homogeneous soil profile. The rotor is considered a Jeffcott (Laval) model with external damping which is attached to a rigid foundation. The foundation is supported by a viscoelastic half-space. The analysis is conducted in the plane of the rotor. A detailed deduction of the system's equation of motion is presented. The soil response is synthesized by the Boundary Element Method. The analysis is conducted in the frequency domain, leading thus to the stationary response of rotor and foundation. The influence of distinct system parameters of the dynamic response of rotor and foundation is addressed. The geometric parameters include the distance of the foundation mass center to the soil-foundation interface and the height of the rotor with respect to the foundation. The effect of rotor to foundation inertia ratio is investigated. The role of soil internal and geometric damping on the system response is also addressed. The influence of the contact type at the soil foundation interface, bonded or smooth, is also considered.

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.
