On April 12, 2022, China High Speed Railway Fuxing CR450 multiple units successfully

achieved a single train speed of 435 km/h and a relative speed of 870 km/h on the open line,

creating a world record for the speed of high-speed rail multiple units trains crossing open lines

and tunnels. The new generation standard EMU "Fuxing" is a new generation of high-speed

train independently researched and developed by China with full intellectual property rights. It

integrates a large number of modern domestic high-tech, and achieves important breakthroughs

in key technologies such as traction, braking, network, bogie, and axle. It is another major

achievement of China's scientific and technological innovation. Figure 1 is a simplified model

of the high-speed rail geometric structure.

The head structure of China's high-speed railway is bullet head, and the duckbill structure

is adopted by Japan's high-speed railway. Figure 2 shows the simplified models of four typical

high-speed railway head structures including the types of TP1, TP2, TP3 and TP4. Among

them, the design of high-speed rail head structure mainly considers air resistance and noise

level.

高速列车优化设计

2022年4月12日，中国高铁复兴CR450多列列车成功实现单列车速435公里/小时，在开放线路上实现相对速度870公里/小时，创造了高铁多列列车穿越开放线路和隧道的速度世界纪录。新一代标准动车组“复兴号”是中国自主研发的具有完全知识产权的新一代高铁列车。它融合了国内大量现代高新技术，在牵引、制动、路网、转向架、车轴等关键技术上取得了重要突破。这是中国科技创新的又一重大成果。图1是高铁几何结构的简化模型。
