Abstract

fetched live from OpenAlex

There are an increasing number of systems available to increase roll stability; however some are not present on all vehicles. Most recent research is focused on ways to improve roll stability, but research into the roll stability of existing vehicles is also important in determining safe operating conditions. This study investigates the roll stability of three vehicles towing a special-purpose trailer currently in use that has no brakes or suspension. Multibody dynamics models of the vehicles were built to simulate vehicle performance on high-speed turns and lane changes. Model validation was performed by comparing results between the simulation and physical testing. Roll stability was assessed by comparing static roll threshold (SRT) and load transfer ratio (LTR) values. All of the vehicles were shown to meet performance standards on a smooth surface, but introduction of surface roughness significantly decreased the roll stability of the trailer due to the lack of suspension.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
