基于计算机仿真的汽车与高速公路护栏碰撞事故的分析与研究

Analysis and Investigation on Car Impact with Highway Barrier Based on Computer Simulation

从高速公路交通事故的统计资料出发,分析了汽车与高速公路护栏事故在交通事故中的比例与发展趋势.通过计算机仿真的方法,研究了汽车与高速公路护栏碰撞过程的汽车与乘员的动态响应和护栏的特性.从提高汽车安全和改进护栏设计等方面,提出了改善高速公路交通安全的措施,指出了本领域的研究展望.

Based on the statistics of traffic accidents on highway, the carbarrier impact accidents on highway were investigated with its proportion and trend in development among domestic and abroad traffic accidents. Using computer simulation,the dynamic responses of car and occupant,and the performance of roadside barriers were studied. The possible countermeasures for highway vehicle traffic safety and the improvement of roadside barrier design are presented.The research prospects in this field are also proposed.
