Abstract

Abstract

In order to obtain the optimal structure parameters of interrupted type straight-road concrete barrier with given length concrete frusta, the orthogonal experimental design method was used, 5 section parameters of the barrier were taken as design variables, each design variable had 5 levels, based on vehicle-barrier collision system dynamics model and LS-DYNA software, vehicle-barrier collision simulation test with 25 group section parameter combinations was carried, and the influence of section parameter combinations on vehicle collision was studied.Simulation result shows that the barriers with 2 group section parameter combinations meet the collision requests that tire and barrier are intact, the head injury criterion is less than 1 000, the barrier has a strong energy-absorption capacity, and can guide the vehicle out of control to the right direetion as long as its design parameters are reasonable, so it has good characteristics for engineering application.
