Full-scale crash testing was performed on Minnesota’s Aluminum Type III Barricade by the Midwest Roadside Safety Facility. Testing consisted of an 820 kg vehicle impacting the barricade at two positions, 0 and 90-degrees, at 100 km/h. This paper documents the modeling effort to simulate the physical crash events using LS-DYNA, a nonlinear finite element analysis program. As is typical for vehicle crash simulation, there were many modeling issues that needed careful attention. Four items of particular concern were (1) contact snagging - the barricade kept hooking on the hood with edge to edge snagging; (2) placement of barricade - small adjustments to the impact location could cause the tire to run over one of the barricade legs, which did not happen during the testing; (3) contact friction - the friction between the barricade and the front of the vehicle played an important role in how the barricade wrapped around and flipped off of the vehicle, and (4) sandbag weight - the weight of the sandbags, which are placed on the legs of the barricade and are used to prevent the barricades from being moved by the wind, makes a difference on how the sign legs flip up into the air when impacted by a vehicle. Simulation results are shown to be fairly accurate for both impact conditions. Future studies on various barricade configurations are now possible using the model developed during this research.
