2005年至今,我国已掌握动车组列车总成、车体、转向架、牵引电机、牵引变压器、牵引变流器、牵引控制、列车网络控制和制动系统等9大关键技术及10项主要配套技术。动车组的国产化程度达到75%以上,在牵引系统、制动系统、高速转向架、车体空气动力学等方面的技术已处于世界领先地位。从赶超到领跑,中国铁路在短短5年时间里,实现了从高铁技术输入国到输出国的完美转身,演绎了自主创新的“中国速度”。
Since 2005, our country has mastered 9 key technologies such as EMU train assembly, bodywork, bogie, traction motor, traction transformer, traction converter, traction control, train network control and braking system and 10 major supporting facilities technology. The degree of localization of the EMUs has reached more than 75%, and the technologies in the traction system, braking system, high-speed bogies and body aerodynamics have become the world leader. From catch-up to lead, China Railway realized the perfect turnaround from the high-speed railway technology importing country to the exporting country in just five years, and deduced the “China Speed” of independent innovation.
