Title: Multi-Body Simulation Modeling of Vehicle Skidding and Roll over for Horizontal Curves on Longitudinal Grades
Accession Number: 01514481
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: The impact of combined horizontal curve and longitudinal grade on skidding and roll over of various vehicles is investigated. A series of simulation tests are conducted using CarSim and TruckSim, which are among the most popular multi-body simulation software packages in the vehicle industry. Two types of behavior for the driving system are considered in the simulations: (1) the driver negotiates the curve at constant speed or (2) the driver needs to brake while passing downgrades. Based on the results, a truck is subjected to greater lateral accelerations on downgrades and lower lateral accelerations on upgrades. Greater side friction factors are seen on downgrades for all vehicles when cornering. Braking has a considerable effect on side friction factors, especially for a sedan car. Braking can be an important threat to the safety of passenger cars (in terms of skidding) and trucks (in terms of rollover).
