摘要:
新型无人驾驶地铁列车为现代轨道交通智能列车的代表，对列车运行安全性，尤其是对列车的碰撞安全性具有较高的要求，是车辆设计的重点和难点。以新型无人驾驶地铁列车为研究载体，以列车耐撞性为研究目标，基于EN 15227：2008标准要求，采用数值仿真分析方法对新型无人驾驶地铁列车耐撞性进行研究评估。研究结论为：列车在初始速度25 km/h下与一列静止列车发生碰撞时，车钩缓冲器、压溃管及防爬吸能装置可以将碰撞动能全部吸收，能够较好地缓冲撞击；列车爬车指标、乘员生存空间指标及减速度指标均满足标准要求，能够保护乘客安全。
Abstracts:
The new unmanned subway train is the representative of modern rail transit intelligent trains. The safety of train operation, especially the collision safety of trains, has high requirements. It is the focus and difficulty of vehicle design. This article takes the new unmanned subway train as an example. The research carrier takes the train crashworthiness as the research target, adopts EN 15227：2008 standard to research and evaluate the crashworthiness of new unmanned subway trains, and uses numerical simulation analysis to conduct a systematic research and evaluation of the crashworthiness of subway trains. Under the collision condition of the initial speed of 25 km/h, the coupler buffer, crush tube and anti-climbing energy absorption device can absorb the kinetic energy of the collision, the car body does not participate in energy absorption, the train climbing index, the occupant living space index and deceleration indicators meet the requirements of the standard. In the event of a collision, the crashworthiness of the train can better cushion the impact and protect the safety of the occupants.
