Analysis on the Crashworthiness of Taiwan PVC Barrier

In this paper, the crashworthiness of the Taiwan PVC barrier was researched using the method of computer simulation according to the domestic evaluation standard. First, from the perspective of comparative analysis, the simulation experiment schemes were determined primarily based on crash test conditions and test factors of the barrier. Secondly, the “vehicle-barrier” model of each group was set up based on virtual proving ground (VPG) pretreatment software, and the safety of impact between vehicle and barrier were studied from the aspects of the moving locus of vehicle, the acceleration of the vehicle, and the maximum lateral displacement of barrier, etc. The analysis results show that the oriented capability of the PVC barrier and the strength provided by the beam were poor and could not resist a collision with a vehicle. Furthermore, the evaluation factor itself could not meet the acceptance criteria. Thus, further research on the material properties and the optimization of the cross section shape of the barrier beam are of great importance.
