Abstract

fetched live from OpenAlex

While operating on rough runways, commercial aircraft landing gear may experience overheating issues on the bogie pivot pin. This thesis is an integrated model that generates the landing gear dynamic behaviour and predicts the temperature of the pin. The integrated model consists of four individual components. Built in MATLAB Simulink, the dynamic model outputs the pin rotation angle and the dynamic loading with a given input runway profile and aircraft characteristics. The structural stress model is an ABAQUS finite element analysis model that determines the contact pressure distribution on the pin contact surface at any given dynamic loading. The dynamic variables and the pressure distribution are collected and used in the heat generation model to calculate the frictional heat generation and distribution. Finally, the heat conduction model in ABAQUS performs thermal analysis to obtain the operational temperature of the bogie pivot pin.

Full frame distilled prediction

Teacher imitation

Not 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.
