摘要:
设计了一种城市轨道交通车辆的模块化吸能结构。介绍了该结构的总体设计方案，以及防爬装置、吸能单元和连接梁的设计方案。通过建模，根据EN 15227—2008标准中C-Ⅱ车型的碰撞工况要求，对该结构进行仿真分析。结果表明该吸能结构可沿着预设变形结构进行变形，最大触发力小于总体要求，塑性变形吸能满足吸能要求；通过对该结构进行试验，结果表明该吸能结构可沿着预设变形结构进行变形，最大触发力略大于总体要求，塑性变形吸能不足。由试验结果可知，需要对该吸能结构进行优化。
Abstracts:
A modular energy absorption structure of rail transit vehicle is designed, the overall design scheme of the structure, the designs of anti-climbing device, energy absorption unit and connecting beam are introduced. In accordance with the EN15227 C II collision requirements, the modular energy absorption structure is simulated and the results show that the structure can deform according to the preset deformation structure, the maximum trigger force of it is less than the overall requirement, and the plastic deformation satisfies the energy absorption requirements. The experimentation result shows the deformation and the maximum trigger force of the modular energy absorption structure can meet the general requirements, but the energy absorption of the plastic deformation is not sufficient, which needs to be improved as a result.
