摘要
汽车与高速公路护栏的碰撞是极其复杂的事件,涉及到人、车和路(护栏)三个方面的因素。对影响汽车—高速公路护栏碰撞事故的有关要素进行分析,在此基础上采用计算机仿真的方法建立了汽车—护栏、乘员—车厢的碰撞模型,对汽车和高速公路护栏的碰撞进行全面的分析。研究不同参数对人体的损伤影响,根据研究结果进一步提出护栏设计和改进的方法,从而降低事故对人体的损伤程度。
An impact between vehicle and roadside barrier is an extremely complex event and it involves in problems of human, vehicle and road (barrier). Based on analysis of factors that have influences on car impact with highway barriers, a mathe-matic method of computer simulation is used to develop car-barrier and occupant-car compartment impact models to study such accidents on highway. A parameter study on dynamics of the car and occupant and injury indices on occupant is carried out. According to the results got previously, improvements for barrier design is presented so as to reduce injury severity to occupant.
