摘要
护栏是重要的交通安全设施,车辆与公路护栏的侧面碰撞是一个较为复杂的事件.为了弥补实物碰撞实验周期长、研究成本高的不足,采用有限元仿真技术对此进行研究.建立了护栏受侧面碰撞的有限元模型并进行了仿真计算分析.将有限元计算所得加速度结果与相应规范中理论计算值进行比较,二者比较接近.结果表明可应用有限元法进行半刚性波形梁护栏受侧面碰撞仿真模拟,为新型护栏的研究开发缩短周期并节约成本.
The semi-rigid guardrail is an important facility for the traffic safety. The side crash between a vehicle and a semi-rigid guardrail is an extremely complex event. Finite element simulation technique could shorten the period of experiment and cut the expensive cost of actual collision. In this paper, the finite element model was built up and the analysis of side crash between vehicle and barrier has been conducted,then the simulation result is compared with the theoritical calculation of acceleration. They are very similar. Therefore, the FEM can be used to simulate the actual collision and to instruct the design of new type barriers. This should shorten the consumed time and save the experimental cost significantly.
