Development and Validation of Offset Deformable Barrier Model with Beam Element

Abstract:

According to GB/T 20913-2007 regulation, the finite element model of the offset deformable barrier (ODB) was built with beam and shell elements, and validated in the simulation of quasi-static compression test. In order to analyze the local deformation characteristics of the ODB model, a sled test was designed. A cylinder impactor of 110 mm in diameter was welded in front of the sled. It was used to impact the fixed ODB. The simulation model of this test was also built. The acceleration of the sled and the deformation of the ODB were measured in the test and compared with the simulation data. The results show that the ODB model with beam elements not only satisfies the demands of the regulations, but also has good local deformation characteristics. The efficiency of computing can be improved obviously with beam elements.
