China's bullet train manufacturing: innovation from starting to surpassing

since 2004, China's railway bullet trains have gone from introduction and trial production to large-scale and industrialized development, and have found a path suitable for the independent innovation of high-speed trains with Chinese characteristics that have been supplied to EOS

The CPC Central Committee and the State Council have always attached great importance to railway development. After the 16th National Congress of the Communist Party of China, the Party Central Committee with Comrade Hu Jintao as the general secretary made a strategic decision to accelerate the development of the railway from the perspective of implementing the scientific concept of development and realizing the overall strategic situation of sound and rapid development of the national economy. In April2004, in accordance with the general requirements of the State Council for introducing advanced technology, joint design and production, and building Chinese brands, the Ministry of Railways concentrated on the advantages of China's railway equipment and then used the micro focusing hand wheel to make the image clear and ready for manufacturing, and launched the largest import, digestion, absorption and re innovation project in the history of railways, so as to speed up the integration of China's railway equipment technology with the world's advanced level

under the organization of the Ministry of railways, 8 new main engines or accessories development enterprises in China's locomotive and rolling stock manufacturing industry have entered the technology introduction sequence. From 2004 to 2005, CSR Qingdao Sifang locomotive and rolling stock Co., Ltd., CNR Changchun rail Co., Ltd. and Tangshan rail car Co., Ltd. successively introduced technology from Bombardier, Kawasaki heavy industries, Alstom and Siemens to jointly design and produce high-speed EMUs. While introducing, digesting, absorbing, and innovating independently, they began the ice breaking journey of China's high-speed rail equipment technology, and gradually mastered nine key technologies and 10 main supporting technologies of the assembly, car body, bogie, traction motor, traction transformer, traction converter, traction control, train network control and braking system of trains with a large gap between the EMU instrument industry and foreign countries, A technical platform for EMU series products has been built

in december2007, the first domestic crh2-300 harmony multiple unit train with a speed of 300 kilometers per hour came out. In april2008, the domestic CRH3 harmony multiple unit train with a speed of 350 kilometers per hour came off the production line, marking that China's railway multiple unit manufacturing technology has made significant achievements

on February 26, 2008, the Ministry of Railways and the Ministry of science and technology signed the joint action plan for independent innovation of China's high-speed trains to jointly develop and operate a new generation of high-speed trains with a speed of 380 kilometers per hour. On may27,2010, in Changchun, China, the first vehicle of the new generation of domestic harmony crh380a high-speed train with independent intellectual property rights and a speed of 380 kilometers per hour came off the production line

before the opening of the Beijing Shanghai high speed railway in 2011, the Ministry of Railways announced that China had fully mastered the key technologies of high-speed bullet trains and had no intellectual property disputes with foreign countries

the high-speed train technology innovation international forum held in Beijing on April 29, 2012 made it clear that during the 12th Five Year Plan period, China's high-speed train technology aims at the development of pedigree, intelligence and green

at present, China's multiple units have obtained a total of more than 1000 relevant patent authorizations. The extensive use of various countries' bullet train technologies has enabled Chinese bullet train manufacturers to have a strong ability to integrate systems, adapt to modifications, comprehensively solve problems and complete localization innovation, and finally form independent technical standards. It shows to the world that yingweida is applying for a patent for this technology: China's railway equipment has achieved a historic transcendence over its existing innovation achievements, and completed the magnificent turn from made in China to created in China
