Curb-to-Barrier Face Distance Variation an a TB51 Bridge Barrier Crash Test Simulation

Abstract

This paper addresses the problem of road safety regarding barrier placement as relative to the curb. A short summary of existing regulations is presented. Numerical simulations using the explicit finite element system LsDyna are shown. In the analysis, variable distance between the barrier and the curb is assumed. The obtained result reveals that the distance has little impact on the working width of the barrier.

On the influence of the acceleration recording time on the calculation of impact severity indexes

“…This method is widely used in modelling vehicle collision against various types of road restrained systems [11][12][13][14]. Validation procedures have been described in European Standards [3,4], their direct use can be found in [15,16]. Validation of the concrete road safety barrier was performed showing that the obtained numerical response is correct.…”

Numerical simulation of the influence of the selected factors on the performance of a concrete road barrier H2/W5/B

“…One of the most popular systems is LS-DYNA explicit dynamic finite element code [3,4]. It is widely used tool for crash tests simulations for various types of road restraining systems [5][6][7][8][9][10][11][12] or other special events [13][14][15][16]. Thus, numerical methods allow engineers to apply the virtual testing environment in broad spectrum of applications aimed at improving the road safety.…”

Finite element method simulations of various cases of crash tests with N2/W4/A steel road barrier

“…Validation procedures have been specified there and precise conditions which numerical simulation must fulfil are listed. The subject of crash tests numerical modelling has already been widely described in the literature [5][6][7][8][9][10][11][12][13][14].…”
