Research on the Crashworthiness of Neotype Flexible Safety Fence

Abstract:

In order to identify the crashworthiness of neotype flexible safety fence, methods was created by conducting FEA (finite element analysis) computer simulation and full-scale impact test based on the current available evaluation standard. Above all, the model of “vehicle-guardrail” was set up based on virtual proving ground (VPG) pretreatment software, the safety in the impact between vehicle and neotype flexible safety fence were studied from the aspects of the moving locus of vehicle, the acceleration of vehicle and the maximum lateral displacement of guardrail etc. Secondly, full-scale impact test was conducted for the guidance quality of guardrail to the tested vehicle. The test results indicated that the neotype flexible safety fence was inconspicuous to the tested-car, which was basically the same to the simulation results, and the evaluation parameter of guardrail met the acceptance criteria.
