| Abstract: | Based on the same material weight, the crash characteristics of expressway safety barriers with different shape were studied. Through dynamic computer simulation, the locus and energy absorbing of small vehicle clashing beam barriers were analyzed. It shows that the beam barriers with 4 semicircle shape get an advantage over 2 semicircle shape on energy absorbing. This conclusion provides foundation for the manufacture and design of barriers. |
