| 摘要： | The Federal Highway Administration has expressed interest in learning more about pavement drop-offs at the edge of roadways and their relationship with the roll stability of heavy vehicles. statistics kept by the National Highway Traffic Safety Administration (NHTSA) and other entities have shown that more than half of all heavy vehicle rollovers are associated with a run-off-road crash. Furthermore, the majority are 'tripped;' that is, the truck rolled over because it ran over a drop-off or encountered a curb or other obstacle. Previous rollover research by the heavy truck rollover consortium (Knee et al, 2005; NTRCI 2009a; NTRCI, 2009b), like nearly all previous full-scale rollover experiments, has focused on the 'untripped' Rollover; i.e., those in which the truck executes a maneuver (such as rounding a corner too quickly) and Rolls on essentially level pavement. This is because the untripped rollovers are simpler to describe, and they are easier and safer to execute in full scale. The proposed research will be the first published experiments in heavy vehicle rollovers resulting from roadway recoveries. The long-term objectives of the recommended research are to: develop and validate a model that explains how and when tripped rollovers occur and the influence of key components, develop recommendations and guidelines for reducing the likelihood of tripped rollovers, including recommendations for: highway and pavement design, vehicle suspension and dynamics design, vehicle suspension and dynamics design, stability control algorithms, driver recovery procedures. / NOTE: Final rept. 09 Mar. - 09 Aug. / Supplementary Notes: Prepared in cooperation with Battelle, Columbus, OH.
