近日，国铁集团在福厦高铁福清至泉州区段组织开展了新型动车组新技术部件在更高运行速度条件下的性能验证试验，试验列车单列最高运行时速达到453公里，标志着CR450新一代动车组研制取得新进展。
Recently, China Railway launched a performance validation experiment for new technical components of new electronic multiple units (EMU) on condition of faster speed in the section from Fuqing to Quanzhou on Fuzhou-Xiamen High-speed Railway. The maximum speed reached 453km/h, marking a breakthrough in the development of CR450 EMU.
6月28日在湄洲湾跨海大桥，试验列车实现单列最高时速453公里、双向两列相对交会最高时速891公里运行；6月29日在海尾隧道，试验列车实现单列最高时速420公里、双向两列相对交会最高时速840公里运行，对新技术部件进行了有效的性能验证，各项指标表现良好，为“CR450科技创新工程”的顺利实施打下了坚实基础。
On June 28th, on the Meizhou Bay Cross-sea Bridge, the test train achieved a maximum speed of 453 kilometers per hour in a single direction and a maximum speed of 891 kilometers per hour in a two-way encounter. And on June 29th, in the Haiwei Tunnel, the test train achieved a maximum speed of 420 kilometers per hour and a maximum speed of 840 kilometers per hour in a single direction and a two-way encounter respectively, which verified the performance of new components with excellent indicators, laying a solid foundation for the advancement of CR450 Technological Innovation Program.
更高时速运行条件下的性能验证试验表明，新技术运用实现了动车组相关指标的新提升，高铁安全、功率、能耗、震动、加速性能、制动平稳性等重要指标持续领先，为研制更高速度、更加安全、更加环保、更加智能的CR450动车组提供了有力支撑，对于实现铁路高水平科技自立自强具有重要意义。
According to the performance validation experiment under a higher maximum speed, newly applied technologies have further improved the indicators of the EMU, enabled the security, power, energy consumption, vibration, acceleration, brake stability and other indicators of high-speed railway to continue to take the lead, and made it possible for faster, safer, greener and smarter CR450 EMU. In addition, it is of great significance to realize greater self-reliance and strength in science and technology of railway.
