Analyse dynamique et conception oréliminaire de moteur bicylindre pour des modes de propulsion propres
Bibliographic record
Abstract
Facing environmental and energy challenges, automotive industry has to improve the fuel economy of vehicles and to reduce their polluting emissions. In this particular context, small twin-cylinder engines regain interest for using in urban cars or as prime movers in hybrid electric cars. One difficulty with engine having few cylinders (three or less) comes from the balancing of the inertia forces created by the moving parts. Several models (from simple analytical model to complex flexible multibody simulation) of different configurations of twin-cylinder engine are developed. These models allow computing the inertia forces and moments generated by the engines and computing the strains and stresses of engine components. An important step is the engine balancing by modification of the crankshaft counterweights or by addition of balance shafts. The effect of the gas pressure on the balancing and on the component’s strains and stresses is also modelled. At the end, a comparison of the different configurations of twin-cylinder engine is provided

How this classification was reachedexpand
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.
