Numerical Evaluation of TRL Barrier’s Compatibility Assessment Capability 2006-01-1133

Barrier impacts are routinely used to estimate the impact response of vehicles in vehicle-to-vehicle crashes. One area of investigation is the detection of the secondary energy absorbing structures provided for under-/over-ride mitigation as a result of increased structural engagement -- improved geometric compatibility. The flat rigid barrier and the Transportation Research Laboratory’s (TRL) full width honeycomb barrier are commonly considered. In the present study, a vehicle-to-vehicle impact that exhibited no under-/over-ride condition was compared to finite element analysis of vehicle impacts to the two different barriers in order to evaluate their ability to detect the secondary energy absorbing structure. This study demonstrates that the rigid barrier and the TRL barrier yield similar quantitative information with regard to vehicle-to-vehicle crashes.
