Simulation of Dynamic Rollover Threshold for Heavy Trucks 2003-01-3385

Two models of a tractor-semitrailer combination are created based on vehicles used in a field operational test. One model is used for tilt table simulations and the other is supplied driving inputs from the field operational test at two dangerous road curves (“hotspots”). Dynamic rollover conditions are simulated for several hotspot trips and varying payload conditions by extrapolating the trip speed profiles.
The dynamic rollover threshold from the vehicle simulations is shown to be, on average, about 25% lower than the static stability factor over the range of loading conditions. The difference between the critical speeds at rollover for the range of loading conditions is approximately 3 m/s.
