Sensitivity Analysis and Improvement of the Rollover Propensity of Large Articulated Vehicles on Roundabouts Using Design of Experiments 02-16-02-0009

This also appears in SAE International Journal of Commercial Vehicles-V132-2EJ

In this article, safe driving methods for large articulated vehicles passing roundabouts are presented using the design of experiment (DOE) method. First, the roundabout driving safety evaluation based on the rollover propensity index calculated with the tire loads was performed through various PC-Crash simulation analysis. And, using the Taguchi method, which is a representative DOE method, major factors affecting the rollover index were set by type and the sensitivity analysis results were quantitatively obtained. Finally, safe driving methods at roundabouts for large articulated vehicles through systematic reduction of rollover propensity were presented, demonstrating that they can be directly applied to advanced driver assist systems.
