Development of N2–H1 Performance-Level Guardrail: Crash Testing and Simulation

In this paper development details of a new lightweight N2-H1 performance level guardrail, called AG04, is explained. A series of computer simulations and crash tests were performed for the crashworthiness evaluation of the AG04 system. A nonlinear multipurpose 3-D finite element code, LS-DYNA, was used for the crash test simulations. After two failed crash tests necessary modifications were made and AG04 guardrail successfully met the criteria outlined in European Normative (EN) 1317-1 and 2. AG04 achieved N2-W3-A and H1-W4-A performance levels when breakaway bolts were used between post and rail. Crash test results showed that AG04 system with both A and B type W-beam rails performed similarly, which indicated either rail type can be used for an acceptable performance. It was concluded that properties of post-to-rail bolt and details of 10,000-kg truck are the most critical parameters for a satisfactory crash test performance for the AG04-2.0 barrier.
