| 摘 要： | 实车与足尺护栏碰撞试验是研究公路护栏安全性最直观和有效的方法,但存在成本高、周期长、重复性差以及检测数据量有限等不足.对轿车与护栏碰撞系统进行有限元建模和仿真,并通过试验验证,主要特征参数具有很高的一致性.根据仿真的结果,能更深层次地分析影响系统安全性的因素,为高速公路护栏的设计、施工、设置以及轿车防撞性能的改进提供有效依据. |

| Abstract: | The test which a real car bumps against full-scale guardrails is the most intuitionistic and effective way for researching the security of guardrails.But there are some deficiencies such as:high-cost,long-cycle, incompletion repeatability and shortage of test data etc.Car bumping guardrail system has been modeled and simulated,and its results approved by test.Both characteristic data have great coherence.On the basis of the results of simulation,we can deeply analyse influencing factors of car bumping guardrail system.It will be beneficial to the guardrail design,construction,setting and car crashworthiness ameliorating. |
