长沙科技助跑“复兴号”
2017-08-27 02:55:47 中国青年网
实车撞击试验,成就安全性能“中国标准”
通过了空气动力学性能测试还远远不够,“复兴号”必须通过耐撞性测试,确保万一发生碰撞事故时乘客的安全。记者在碰撞实验室的西头看到,两节全尺寸的“复兴号”火车头对撞在一起,除车头鼻尖位置外,其他部位完好无损。
梁习锋告诉记者,“复兴号”的车头、车尾以及中间车都搭载了专用吸能装置,就像汽车的保险杠一样,它能吸收撞击产生的能量,从而保证了中间载人部分的安全。
据悉,目前我国所有的车辆耐撞性试验全部在这里完成。“复兴号”前后经历了多次撞击试验,每一次试验结果都为下一次的改进提供了大量宝贵数据,可以说“复兴号”是在“试验——受伤——进步”的循环中不断升级,最终通过了耐撞性测试,成为性能优异的新一代安全列车,并形成了“中国标准”。
本期实验室名片
中南大学轨道交通安全教育部重点实验室开辟了我国轨道交通空气动力学、列车撞击动力学研究领域,同时对列车控制与测试技术、交通运输组织与信息系统开展深入研究。2016年11月,以该实验室为依托,由中南大学和中车四方股份有限公司、澳大利亚莫纳什大学、美国交通技术研究中心、英国伯明翰大学联合组建的轨道交通安全国际合作联合实验室,已通过教育部组织的立项论证。
