Finite element modeling of the crash performance of roadside barriers
Tóm tắt
Crashworthiness of a modified W-beam guardrail design is evaluated in this paper. In this analysis, a detailed finite element model of the guardrail was developed and the crash response simulated when impacted by a pick up truck traveling at 100 km/hr. A finite element model of a Chevrolet C2500 pickup truck was combined with the guardrail model to simulate the crash test. The combined model evaluation focuses on comparison of actual crash test data with the simulation results in terms of roll and yaw angle measurements. Simulation results were found to be in good agreement with the crash test data. Additionally, simulations were also performed to evaluate the effect of certain guardrail design parameters, such as rail mounting height and routed/non-routed blockouts, on the crashworthiness and safety performance of the system.
