摘要:
为了改进某城市轨道车辆车体耐碰撞性能,根据美国AAR S-034标准要求,建立了一种基于蜂窝铝芯和锥形薄壁方管结构的碰撞能量管理(CEM)系统,利用LS-DYNA平台,对该CEM子系统的撞击性能进行了分析,并对比了安装CEM系统前后整车撞击刚性壁障的界面力-位移曲线和加速度-时间曲线。研究表明:“铝芯-薄壁管”组合式吸能结构可以使压溃变形过程有序进行,且具有较低的撞击力初始峰值;采用文中的CEM系统可显著提高车体端部结构的耐碰撞性能。
Abstract:
In order to improve the crashworthiness performance of a mass transit vehicle body, a crash energy management (CEM) system based on honeycomb aluminum core and tapered thin-walled square tube structure was established according to the requirements of American AAR S-034 standards. And the impact performance of CEM subsystem was analyzed by using the LS-DYNA platform. Then, the force-displacement curve and acceleration-time curve of the vehicle before and after the installation of the CEM system were compared under the scenario of impacting with a rigid obstacle. This research showed that, the "aluminum core-thin wall tube" combined energy-absorbing structure can make the crushing deformation process in an orderly manner and has a lower initial peak impact force; using the CEM system designed could significantly improve the crashworthiness performance of end structure of the vehicle.
