Technical R & D and industrialization and "undertaking" of high-speed railway equipment manufacturing by CRRC Sifang

From the opening and operation of the first high-speed railway with a speed of 350 kilometers per hour more than ten years ago to the independent development of "Fuxing" Benz in the vast land in recent years, dozens of core technologies and products of CRRC Qingdao Sifang Vehicle Research Institute (hereinafter referred to as "Sifang Institute") have made great contributions

Sifang Institute keeps pace with the development of railway and rail transit in China. It is understood that in 1959, the former Ministry of Railways established Sifang Rolling Stock Research Institute, which focuses on the research and product development of rolling stock technology. The only professional research institute of rolling stock in China is composed of technical elites from all over the country, excellent teachers and students from key domestic colleges and universities, and overseas students. After 60 years of development, Sifang Institute has grown into a technical leader in the field of China's rail vehicles, based on the core system equipment of rail transit and synchronized with the national development strategy In 1995, the state proposed the construction plan of Qinghai Tibet railway, and Sifang institute undertook the research and development of the complete set of electrical technical equipment and oxygen supply scheme for Qinghai Tibet railway. In order to overcome the high altitude, large temperature difference and strong sandstorm, Sifang Institute of science and technology has put forward two kinds of oxygen supply modes of dispersion type and concentration type and the overall scheme of train electrical system, which has solved the worldwide problems of electricity and oxygen supply in the world's highest altitude area, and therefore won the special prize of national science and technology progress award.

in the overall situation of independent innovation of high-speed railway, the electrical system, damping and coupler damping system independently developed by Sifang Institute have been successfully equipped with high-speed railway lines, and the core technical products such as traction converter, network control, braking, coupler damping and damping have been listed as "Renaissance". In terms of urban rail transit, Sifang Institute has realized the integration of urban rail train traction, braking and network control for the first time, becoming the only technical provider in China to realize the integration of three systems. It has been loaded in many cities in China and realized integrated operation, which has changed many problems and led the industry in market share Kong Jun, Secretary of the Party committee and chairman of the board of directors of the

Sifang Institute, said that based on the advantages of technological innovation, we can realize the industrial growth rate and achieve greater economic and social benefits; the economic strength and big data accumulation brought about by industrialization, in turn, feed technological research and development and promote technological innovation, which is the internal driving force for the development of Sifang Institute. It is reported that Sifang Institute has won more than 200 national, ministerial, provincial and municipal science and technology progress awards, including the national science and technology progress award, with 490 authorized patents, including 63 foreign invention patents.
