| 中文摘要 | 基于非线性有限元方法进行碰撞仿真的原理,针对某型号客车详细阐述了整车有限元模型的建立,依据欧洲ECE R66法规要求进行了客车动态翻滚碰撞过程的仿真研究,评价了该车的上部结构以及乘员生存空间是否存在侵入,仿真分析与理论分析的能量曲线取得了较好的一致,说明该有限元模型是准确的。根据仿真计算结果,对顶横梁、窗立柱等结构进行改进设计,有效提高了其抵抗变形能力,改善了该车的侧翻安全性能。研究结果对客车结构侧翻安全性的优化设计具有重要指导意义。; Based on the basic theory of vehicle crash analysis using the nonlinear finite element method,a finite element model of a passenger bus is built in detail.A dynamic rollover crash analysis of the bus is performed successfully according to the European regulation ECE R66.The deformation of superstructure and intrusion of the passenger residual space is investigated.The good coherence between the simulation result and the theory result in energy indicates that the finite element model is valid and accurate. Based on the simulation result,some design improvements and reinforcements of roof horizontal beams and window pillars are achieved.The capability of preventing the bending deformation is enhanced,and the bus rollover crash is improved greatly.Research result is a guide to realize the optimum design of the crashworthiness for bus rollover crash. |
