打造性能更优新一代CR450高速动车组助推中国高铁事业“十四五”更大发展

Creating a New Generation of CR450 High-Speed EMUs with Better Performance Promoting Greater Advances of CHSR during the 14th Five-Year Plan Period

20世纪90年代至今,中国高速动车组经历了自主探索、引进消化吸收、自主创新、全面创新四个发展阶段,成功实现了从追赶到领跑的历史性跨越。特别是2012年起,为贯彻落实习近平总书记的重要指示精神,中国高速动车组技术进入全面创新阶段。在中国国家铁路集团有限公司、中国中车股份有限公司等组织下,中车长春轨道客车股份有限公司联合国内外科研院所和全产业链供应商,加大自主创新力度,以中国标准为主导,按照正向设计思路,以自主化、简统化、互联互通互换、技术先进为目标,成功研制出具有完全自主知识产权的时速160 km、250 km、350 km系列化“复兴号”动车组,创造了时速420 km列车交会试验的世界记录,实现了全球首个时速350 km商业运营,“复兴号”动车组成功奔驰在祖国广袤的大地上。

Since the 1990s,China′s high-speed EMU have undergone four development stages:autonomous exploration,introduction and absorption,independent innovation,and comprehensive innovation,thus successfully making a historic breakthrough from struggling from chasing to taking the leading position.Especially since 2012,China′s high-speed EMU technology has entered a comprehensive innovation stage to implement the spirit of the important instructions of Secretary General Xi Jinping.Organized by China Railway,CRRC Corporation Limited,etc.,and guided by Chinese standards,CRRC Changchun Railway Vehicles Co.,Ltd.cooperated with domestic and foreign research institutes and suppliers of the whole industry chain to strengthen the independent innovation and successfully developed a series of"Fuxing"EMU with completely independent intellectual property rights(IIPR)at different speeds of 160 km/h,250 km/h,and 350 km/h for the purpose of achieving autonomy,simplification,interconnection and interchange,and advanced technology in accordance with forward designs.Consequently,a world record for the train passing test at a speed of 420 km/h was made,and the world′s first commercial operation at a speed of 350 km/h was realized.The"Fuxing"EMU successfully operate on the vast land of China.
