大西高铁原平至阳曲段冲高试验最高时速达385公里
2017-08-29 04:46:00 中国青年网
本报8月28日讯(记者 赵德伟)昨日,记者了解到,在完成了历时两年多的高速铁路冲高试验后,日前,大西高铁原平至阳曲段现已由试验段转为工程线,正在进行开通前的250公里/小时线路工程恢复和剩余工程施工。
众所周知,新型动车组正式投入运营之前,其原型车都需要经过数万公里的安全运行试验,从而保证其各项设计能够满足载客运营的需要。2013年,中国铁路总公司将大西高铁原平至阳曲区间作为高速铁路冲高试验段,专门搭建综合试验环境,在该铁路线上试验具有完全自主知识产权、时速350公里的中国标准动车组。
大西高铁原平至阳曲试验段正线里程93公里,自2015年8月31日投入使用,截至目前,已历时710天综合试验,共组织开展了十大类80项科学试验,累计开行各类试验列车1.6万多列次,试验总里程达100万公里,最高时速385公里。
其间,综合试验围绕中国标准动车组、高铁地震预警系统、自主化列控系统等重大装备自主化需求,采用正向研究、正向设计、正向制造的科学理念,在动车组装备、工务工程、通信信号、牵引供电、振动噪声、灾害监测等多个领域进行科学试验,取得了一系列丰硕成果。
其中,“复兴号”中国标准动车组已在京沪高铁投入运营,自主化列控系统已完成基本功能测试验证,高铁地震预警监测系统完成了为期一年的试用考核。
铁路部门相关负责人介绍,大西高铁原平西至阳曲西段,因其有着建造标准高、区域位置优越、地形条件适宜等特点,近年来被中国铁路总公司和中国中车集团选定为我国新型动车组的综合性能试验路段。目前,全国综合性能试验路段,仅山西这一段。
