地铁车辆前端吸能系统设计研究

国内目前某B型车项目为满足列车的被动安全要求,提高地铁车辆安全等级,根据EN15227标准,综合考虑列车碰撞总能量分配、各系统吸能界面的平台力、触发次序和吸能行程等,对车辆前端吸能系统进行设计。依据多体动力学理论建立数学模型,对车辆进行碰撞过程仿真计算,验证车辆前端吸能系统设计的合理性,结果证明设计能够满足EN15227标准的要求。

According to a domestic B-type vehicle project, in order to meet the passive safety requirements of trains and improve the safety level of metro vehicles, the front-end energy absorption system of vehicle is designed in accordance with EN15227 Standard by considering the total energy distribution of train collision, platform force, trigger sequence and energy absorption stroke of energy absorption interface of each system. According to the theory of multi-body dynamics, a mathematical model is established to simulate the collision process of the vehicle, and the rationality of the design of the front-end energy absorption system is verified. The results show that the design can meet the requirements of EN15227 standard.
