Collision Simulation to Road Safety Barrel Based on LS-DYNA

Abstract:

The finite element method was used to analyze the crash simulation of road safety barrel in this paper. According to the road safety barrel standard of China—GB/T 28650-2012, 3D software AUTOCAD was used to establish collision system model. By using the project software ANSYS/LS-DYNA to simulate the different wall thickness of road safety barrel, the stress and strain, energy variation and deformation are analyzed for different number of road safety barrel, the layer of road safety barrel wall and road safety barrel in different circumstances. The simulation results may uncover the reasonability of the current road safety barrel set and provide the basis for further improvement.
