China Academy of Railway Sciences Group Co., Ltd. was founded in 1950. It is the only multi-disciplinary and multi-professional comprehensive research institution in my country's railways. At present, it has developed into a large-scale scientific and technological enterprise integrating scientific and technological innovation, technical service, achievement transformation, consulting and supervision, testing and certification, personnel training and other businesses.
Taiyuan Heavy Machinery Group Co., Ltd. was founded in 1950. It is the first heavy machinery factory designed and built by New China. It is a national super-large backbone enterprise. It has 3 national invention awards, 17 national achievement awards, 11 national science and technology progress awards, and 82 national patents, creating more than 340 domestic and foreign first.
Italy Lucini Steel Products Group was founded in 1856 and headquartered in Lawwell, Italy. It is a wholly-owned subsidiary of SINPAR S.P.A Company of Italy. The company is mainly engaged in the manufacture of castings and forgings for oil and gas petrochemical, power generation, shipbuilding and other industries, as well as the design and production of high-end locomotive parts. It is one of the world leaders in the industry.
Zhiqi mainly develops, produces and overhauls wheelsets, axles and other parts and their related parts (including bearing assembly and brake disc assembly) for high-speed trains, EMU trains, urban rail vehicles and other railway vehicles. Among them, EMU wheelset products cover all speed levels, and are widely used in "Harmony" EMU and "Fuxing" Chinese standard EMU, and follow the pace of China's high-speed rail "going out" to provide support for the implementation of the "Belt and Road" strategy. Urban rail products represented by flexible wheels and wheelsets are used in Beijing Xijiao Line and Fangshan Line, Shenyang Hunnan Line and Izmir Project in Turkey, and provide maintenance services for subway wheelsets in many large and medium-sized cities.
Zhiqi Company has established a laboratory with third-party testing qualification, and has the capabilities of full-size axle test verification, full-size wheel test verification, material chemical composition detection, material low-power tissue detection, material energy spectrum composition detection, material microstructure detection, material mechanical property detection, wheel set online detection, non-destructive detection, product failure analysis, vibration and modal analysis, acoustic experiment, paint film test, various sample processing, etc.
The theoretical research and technology development of wheelset design, performance verification technology development, research on the influence of wheelset component defects on safety margin and safety guarantee technology, research on failure mechanism and prevention technology of high-speed wheelset, research on new high-speed wheelset materials (localization direction), research on the matching of wheelset products and application environment, etc. The high-speed EMU wheelset type test operation test system has been developed, and the design and construction capabilities of the full-size high-speed EMU wheel and axle fatigue performance type test and test system have been formed. Participated in the demonstration, design, safety verification, technical review, standard formulation and operation assessment of China's standard EMU. Successfully declared the provincial technology center, and successfully passed the municipal innovation demonstration enterprises and high-tech enterprises identified.
Zhiqi company has a strong quality assurance team, respectively engaged in quality system, size inspection, non-destructive testing, measurement and other work. The company has established a high-standard quality management system, and has successively passed the qualification certifications of ISO9001 quality management system, ISO/TS 22163 quality management system, CRCC, AAR product quality management system, etc.; equipped with advanced wheels, axles, wheel sets and other intelligent testing equipment to ensure product safety and stability.
Zhiqi Company has introduced modern enterprise management concepts and methods such as balanced scorecard, operation management, comprehensive budget management, lean production management and project management. Through ERP, manufacturing execution system and intelligent decision analysis system, Zhiqi Company has realized the integration of business and finance, the integration of production and procurement, and the paperless business approval process and production process. The company actively carries out the construction of intelligent manufacturing of high-speed rail axles, and relies on advanced manufacturing systems and intelligent analysis systems to accelerate the comprehensive digitization and intelligent process of production execution, process control and enterprise management; the company independently developed the wheel set full-size measuring machine and axle full-size measuring machine, realizing the automation of the measurement process and the automatic transmission of measurement results; exploration and practice in intelligent manufacturing, it has greatly improved the company's production and management efficiency, and has a good demonstration effect on the intelligent upgrading and transformation of the rail transit equipment industry.
