摘　　要：EN 15227标准规定了能减少碰撞事故的被动性安全要求,为测定铁路车辆的车体所能承受的碰撞条件提供了框架。新标准EN 15227—2020较其旧版标准新增了排障器的吸能要求,满足新标准的载客列车能更好地保障乘员的安全。该文基于一款200 km/h速度等级的市域车排障器进行有限元分析,以确定该排障器满足标准EN 15227—2020对排障器的静载荷、过载吸能性能的要求。The EN 15227 standard specifies passive safety requirements to reduce collisions and provides a framework for determining the collision conditions that a railway vehicle body can with stand.The new standard EN 15227-2020 has added the energy absorption requirement of the exhaust device compared with the old standard,and the passenger trains that meet the new standard can better protect the safety of the passengers.This paper conducts finite element analysis based on a 200 km speed class commuter vehicle cowcatcher to determine that the cowcatcher meets the requirements of standard EN 15227-2020 for static load and overload energy absorption performance of the cowcatcher.
