Rollover of Heavy Commercial Vehicles
Author: C. B. Winkler
Publisher:
ISBN:
Category : Electronic systems
Languages : en
Pages : 57
Book Description
The state-of-the-art understanding of rollover of the commercial vehicle is reviewed. Accident statistics are presented which highlight the severity and lethal nature of rollover crashes. Physical and statistical evidence for the linkage between vehicle roll stability and the actual occurrence of rollover accidents is presented. The fundamentals of static roll stability are described in detail and then enhanced with discussion of dynamic considerations of the rollover process. The text concludes with a discussion of the evolving use of intelligent electronic systems and active vehicle control for reducing the occurrence of rollover. Appendices include a bibliography of the literature on heavy-vehicle rollover.

A Synthesis of Safety Implications of Oversize/overweight Commercial Vehicles
Author:
Publisher: AASHTO
ISBN: 1560514663
Category : Commercial vehicles
Languages : en
Pages : 113
Book Description
The objective of this report is to identify known relationships between commercial vehicle safety and crash causation factors and to prepare a synthesis of safety implications of oversize/overweight (OS/OW) commercial vehicles. This information can be used to support commercial vehicle enforcement and permitting practices and justify expenditures and investments on size and weight enforcement to enhance safety. In producing this report, insight was gained into the impacts of truck size and weight (TSW) regulations through three case studies. The state of practice in estimating large truck crash rates is complicated because of the many configurations and the wide range of possible weights for any particular configuration. This report highlights four primary findings regarding the contributions of OS/OW to commercial vehicle crashes found by its researchers.

Book Description
"The effect of changes in the suspension of a cargo tank semitrailer on its roll stability was studied in experiments and modeling. Three configurations were considered: a typical design; a design with a wider track; and a design with wider track and greater separation between the air bags. All configurations used new generation wide base single tires (NGWBST). The experiments consisted of a steady state "ramp" steer, a transient "step" steer, and a more challenging dynamic "double lane change" maneuver. Lumped parameter and flexible body models of the combination vehicle were developed and exercised. Widening the track of the semitrailer's axles raised the threshold for lifting a tire from the pavement, as predicted. Moving the suspension's air bags farther apart changed several characteristics of the behavior, with no consistently measurable changes in wheel liftoff threshold. Limited testing with electronic stability control (ESC) showed that the suspension changes did not affect ESC performance. The damping of the trailer roll oscillation provided by the suspension itself was greater than the damping provided by the shock absorbers. This auxiliary damping was generated, at least in part, by the restricted movement of air between the suspension air bags. This work is the final in a series of studies funded by NTRCI to characterize the roll behavior of heavy vehicles and develop computer simulation models to explain that behavior. Previous studies have explored the behavior of a van semitrailer, a flatbed semitrailer, and a tank semitrailer"--Technical report documentation page.
