中国高铁:书写时代名片

2017-07-20 11:00:46   新华社

中铁总科技管理部主任周黎表示,此次试验进一步验证了中国标准动车组整体技术性能,特别是首次实现了动车组牵引、制动、网络控制系统的全面自主化,表明中国具备设计制造满足世界各国不同需求动车组的能力。

国家勘察设计大师、铁四院副院长王玉泽告诉记者,中国建设了一大批适应各种特殊气候环境、复杂地质条件和不同运输需求的高速铁路,技术实力得到充分验证。以铁四院设计建设的郑徐高铁为例,这是国内首条全线采用我国具有完全自主知识产权的CRTSIII型板式无砟轨道施工的高铁项目,有力地展示了中国高铁的整体实力。

“郑徐高铁全线铺设了127192块CRTSIII型轨道板,这种轨道结构整体平稳,安全性更高,耐久性完好,给乘客带来更高的舒适度,整个轨道的综合指标在全国铁路中位居首位。”王玉泽说。

今年6月26日,中国标准动车组“复兴号”在京沪高铁两端的北京南站和上海虹桥站正式亮相,分别担当G123次和G124次高速列车。“‘复兴号’是由中国铁路总公司牵头组织研制、具有完全自主知识产权、达到世界先进水平的中国标准动车组。”何华武表示,中国标准动车组完成了整车60万公里运用考核,欧洲一般只有40万公里,其性能指标实现较大提升,设计寿命由现在的20年提高到30年。

“‘复兴号’将是中国高铁‘走出去’的主力车型。”何华武说,经过多年成网运行,中国高速动车组早已“久经沙场”,既无惧大漠风沙,也适应高寒高热。“复兴号”可以经受零下40℃到40℃的环境考验,也能根据各地自然、经济特征做适应性调整。
