摘要:
针对近年来我国校车追尾事故多发的现状,利用ANSYS/LS-DYNA软件对某款校车防撞钢梁进行碰撞仿真分析,研究在不同速度下追尾碰撞时防撞钢梁变形的规律和特点.研究表明:该校车在低速、中速和高速3种速度情况下发生追尾碰撞,对车体乘员产生不同的冲击和影响,横粱及支架吸收了不同的能量,产生了不同程度的变形.研究结果可为校车减少后防撞钢梁盲目设计和后续优化设计提供一定的理论依据.
Abstract:
In view of the frequent school bus rear-end collisions in recent years,this paper is intended to ana-lyze the result of crash simulation test on anti-collision beam of one type of the school bus and study the ruleand characteristic of the transformation of anti-collision beam in rear-end impact tests at different speeds basedon the ANSYS/LS-DYNA system.The research shows that rear-end collisions between this type of school bushappening at different speeds ( low speed，medium speed and high speed) will have different influences on thepassengers on the bus and that because the cross beams and stands absorb different amounts of energy duringrear-end collisions happening at different speeds,they will have different levels of deformation.The researchresult can provide theory basis for follow-up optimal design of rear anti-collision beam of school bus to some ex-tent.
