摘要:
 为了提高城轨车辆司机室端部主吸能结构的吸能性能,采用仿真分析的方法对底架端梁和吸能结构的板材厚度进行了优化设计。考虑优化部位对吸能量的影响,建立某城轨车辆司机室车与司机室车以25 km/h 相对速度的正撞模型,通过碰撞分析计算得到了结构优化前后的吸能量及车体不发生压溃的最大撞击速度。研究结果表明:提高底架端梁结构的刚度,减小主吸能结构的板材厚度能够满足司机室端部吸能系统的顺序可控变形规律,其吸能性能也得到提升,为主吸能结构的优化设计提供了理论参考。
Abstract:
 In order to improve the energy-absorbing performance of the main energy-absorbing structure at the cab end of the of urban rail vehicles, the underframe end sill and the sheet thickness of the main energy-absorbing structure were optimized by means of simulation analysis. Considering the influence of optimal location on energy absorption, the collision model of cab car versus cab car modal of one urban rail vehicle with a relative velocity of 25 km/h was developed. The maximum impact velocity without crushing and the energy absorption before and after structural optimization were obtained by collision analysis and calculation. The results showed that increasing the stiffness of the underframe end sill and reducing the sheet thickness of the main energy-absorbing structure can satisfy the orderly controllable deformation law of the cab end energy-absorbing system, as well as the energy-absorbing performance can be improved, which provided a theoretical reference for the optimization design of the main energy-absorbing structure.
