摘要:
［目的］为了有效降低城市轨道交通列车发生碰撞时的危害，从而提高列车运行的安全性，有必要对列车运行过程中的碰撞性能进行研究。［方法］基于城市轨道交通列车碰撞场景及标准，提出列车碰撞能量管理方案。利用有限元软件进行列车碰撞场景仿真计算，对列车碰撞时的速度、车辆界面力、车钩力、车辆变形量及应力、应变等进行分析。［结果及结论］在列车车速为25km/h的碰撞过程中，车辆乘客区最大变形量发生在车6，最大变形量为12.2mm，且为弹性变形，远小于EN15227：2008+A1：2010《轨道交通车体的耐撞性要求》要求；车辆最大塑性应变发生在车6端部，为4.7%(小于EN15227：2008+A1：2010规定的10%)，车辆在碰撞过程中满足EN15227：2008+A1：2010对生存空间的要求；轮对最大抬起高度发生在车5后转向架，最大抬起高度达到10.5mm，但未超过轮缘高度的75%，不存在爬车的风险。所提列车碰撞能量管理方案满足EN15227：2008+A1：2010对车辆耐撞性的要求。

［Objective］ In order to effectively reduce the hazards from the collision of urban rail transit trains and thereby improve the safety of train operation, it is necessary to conduct research on the collision performance of urban rail transit trains during the operation process. ［Method］ Based on urban rail transit train collision scenarios and standards，a train collision energy management scheme is proposed. The finite element software is utilized to conduct simulation calculation of train collision scenarios, the speed, vehicle interface force, coupler force, vehicle deformation amount, stress and strain in trains collision are analyzed. ［Result & Conclusion］ During the collision with the train speed of 25 km/h, the maximum deformation in the passenger area of the vehicle would occur in Car 6. This elastic deformation could reach 12.2 mm, far less than that specified in EN 15227:2008+A1:2010 Railway applications-Crashworthiness requirements for urban rail transit vehicle bodies . The maximum plastic strain of the vehicle occurring at the ends of Car 6 is 4.7%, less than 10% as specified in EN 15227:2008+A1:2010. Therefore, the vehicle meets the requirements for the survival space specified in EN 15227:2008+A1:2010 during the collision. The maximum lifting height of the wheelset at the rear bogie of Car 5 reaches 10.5 mm, not exceeding 75% of the flange height, thereby without the risk of vehicle climbing. The proposed collision energy management scheme satisfies the requirements for vehicle crashworthiness in EN 15227:2008+A1:2010.
