| 摘 要： | 实车与足尺护栏碰撞试验是研究公路护栏的安全性最直观和有效的方法,其本质上是以实际交通事故再现的方式分析碰撞前后汽车相对护栏的运动状态和乘员伤害情况。通过实车与足尺钢索护栏的碰撞试验,用小波变换方法分析碰撞过程中的非线性、非稳态信号,能够较为准确的研究护栏、汽车和乘员的动态响应特性。结果表明钢索护栏完全符合要求,为高速公路护栏的设计、施工以及在不同地点的设置提供有益的借鉴。 |

| Abstract: | The impact test with real car and full-scale guardrail is the most intuitionistic and effective way for researching the security of guardrail.It is essentially a kind of reconstruction of traffic accident so as to analyze the movement of car relative to guardrail and injury of occupants during the course of impact.The impact experiments are executed under the conditions of the Wire Rope Fence,non-linear and non-stability signals in the impact are analyzed with the ways of Wavelet-Transform,the dynamic characteristic and the relations among fence,vehicle and occupants can be exactly studied.The results are benefit for the design of vehicle and fence. |
| Keywords: | traffic engineering wire rope fence wavelet transform performance criterion(PC) car impact |
