  图为中国高铁

  “世界高铁看中国”说起高铁,由于高铁市场最初由日本和德国所控制所以我国高铁起步较晚,但是随着我国高铁的快速实现弯道超车拥有世界最长的高铁运营里程。

  历经几十年的建设,中国拥有多张亮眼的名片,其中最让人感受深刻的想必就是高铁。截止2017年,高铁总里程达到2.6万公里占总高铁的三分之二居世界第一位,我国打算在2025年总里程达到4公里。目前我国已经成为唯一高铁成网运行的国家,我国的高铁领域拿下世界第一,所以说我国高铁成为国内外家喻户晓的世界知名品牌。

  施工建设,车辆制造,信号控制等一系列环节使得高铁成为了一项复杂的工程,充分表明中国高铁超乎寻常的技术。那么中国又是如何做到的呢?采用了哪些技术呢

  一. 工程建造技术

  由于我国地理环境的不同,在建造桥梁,公路和铁路上积累的经验不少,拥有了世界最全面的桥梁设计建造和先进现代化装备所以中国也拥有了“基建狂魔”的称号。

  二. 高铁动车组技术

  2000年之后我国就开始研发高速动车组,自主设计了不少车组例如先锋号和中华之星等。直到06年技术加以提升于是批量生产和谐性动车组。为了使整个列车阻力降低,采用的是全新低阻力流线型头和车体平滑设计,使得最后降低了7.5%到12.3%之间。

  三. 列车控制技术

  为了保证动车组正常运行和人员安全,列车控制是一项重要环节。2004年中国构建的列车控制体系达到世界顶尖水平,能够满足300km/h以上的要求。

  四. 牵引电技术

  中国建成了能够满足列车大编组和重连运行需求的世界上最大规模的高速铁路牵引供电数需采集和键控制系统,持续速度350公里。

  1月7日,中车唐山公司研制的新型无线供电式轨车实现从“有线”到“无线”的新产品亮相,它打破发达国家对轨道车辆无线供电式的技术垄断;另一个亮相的是第七代时速200公里的磁浮列车,它完美整合了中低速和高速磁浮的技术优势实现多项关键技术的创新突破。这两大新产品填补了行业的空白是继10年前创下“世界铁路运营实验最高速”的又一奇迹。

  走进中车唐山公司铝合金厂,我们可以看见新兴工业机器人,车体打磨需要工作人员用千叶片,刮刀反复打磨,根本不看是男是女,这是一项十分挑战的工作也是高速动车组车体生产过程中必不可少的工序。我们现在的技术攻关基本上都是靠机器人,这也将是今后高速动车将实现“智能制造”的突破点,经过近3年的摸索,机器人已经代替手工打磨车体,智能化的车体制造生产线已经投入使用。

  “有种速度叫中国速度,有种自豪叫中国高铁”。高铁这长“时代名片”,加快了我国的经济发展,惠及了人民。但是不得不说,高铁有舰艇离不开每一位工程人员的默默付出,希望未来的高铁发展将会为我们创下一个又一个奇迹,让我们一起来见证中国之“快”!
