摘　　要：基于欧洲列车耐撞性评价标准EN15227,分析某8辆编组高速列车3种典型的碰撞工况。借鉴汽车领域乘员安全评价方法,评估高速列车乘员在3种碰撞工况下的安全性,结果表明在3种典型碰撞工况下乘员是安全的。借鉴美国通勤列车座椅标准和美国校车座椅设置及碰撞保护标准,研究座椅间距、椅背刚度、安全带等对高速列车乘员碰撞安全性的影响,研究结果表明:座椅间距太大或太小对乘员安全性均不利;而较小的椅背刚度对乘员二次碰撞有一定保护作用;安全带可大幅降低乘员二次碰撞危险性,建议在高速列车座椅上使用安全带。According to the European train crash worthiness evaluation standards EN15227, three classic scenar- ios of crashing conditions of a high-speed train made-up of eight coupled cars were simulated and analyzed. With the help of the crew ＆ passenger safety evaluation method in the auto industry, the safety of the persons on the high-speed train in the above three classic scenarios of crashing conditions was evaluated and the results proved that the crews ＆ passengers were safe. Using the USA standards for seating in commuter rail cars and for seating and crash protection of school buses for reference, the influences of seat spaces, stiffness of seat backs and seatbelts on the safety of crews ＆ passengers were studied. The results show as follows： Too large and too small seat spaces are both unfavourable for the safety of crews ＆ passenger; less stiffer seat backs are helpful to protect crews＆ passengers in the secondary collision; seatbelts may reduce the danger of the sec- ondary collision by a large margin, so seatbelts are proposed to be installed in high-speed trains.
