Paper Title:
Research on Design of Neotype Wire Rope Safety Barrier
  Abstract

In order to research and develop a suitable wire rope safety barrier for our country, which will be used as the highway flexible safety barrier for two model demonstrative project of science and technology of Changsha-Xiangtan Highway, the paper presents a new type of wire rope safety barrier, by way of designing the shape of the post, the diameter of the rope, the arrangement and the number of ropes etc., on the basis of the form of structure of the most advanced foreign existing wire rope safety barrier — BRIFEN. The first part is devoted to prove the reliability of the finite element simulation, by comparing the simulation results of the finite element model of BRIFEN with the collision test data, which is published by U.S. Federal Highway Administration. After discussion and analysis, the neotype wire rope safety barrier, which has many posts with C-shaped cross section and 5 ropes, is invented with the post equivalent method. The finite element model of the neotype barrier is established and simulated to determine the dimension of the post. The simulation results achieve the design objective that the maximum dynamic deformation is less than 1.2m when the barrier is impacted by the 10 tons of bus in the speed of 60 kilometers per hour, and provide an important reference for Vehicle Crash Test.
