Abstract
The concept and goal of virtual prototyping is to develop a mechanical product as an integrated system entirely using computer methods thus avoiding the necessity of building engineering model prototypes and instead to proceed directly to production hardware. This particular paper refers to mechanical/structural systems which are subjected to any kind of mechanical loading/force or velocity/acceleration input. The example (Figure 1) we shall use to demonstrate the approach is the wheelchair lift design of SIDDHIS Aviation Design Inc. of Dorval, Quebec. This product is designed to provide the Canadair Challenger series of aircraft with the ability to board and deplane a disabled passenger and wheelchair with a combined weight of 180 kg (396 lb). The wheelchair lift is a new product and has been sold and is fitted to a Canadair Challenger CL600 aircraft. This first optimized high strength aluminium chairlift prototype used the ADAMS/ANSYS virtual prototyping strategy and was fitted to its intended aircraft with the only minor modifications to some detail parts being required during the acceptance testing prior to delivery and installation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
