摘要
针对高速公路的波形防护栏,在材料总重量保持不变的情况下,研究不同结构形式下撞击特性,通过计算机对撞击过程的进行动态仿真,对小型乘用车与波形护栏的撞击轨迹和能量吸收进行了分析,结果显示出2半波与4半波防护栏在撞击能量的吸收方面存在较大差异,其结论对防护栏的制造和设计提供依据。
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.
