Verilən məlumatlara görə, saatda 400 kilometr sürətlə sərhədlərarası əlaqəli yüksək sürətli EMU'lar, 13-də Elm və Texnologiya Nazirliyinin əsas xüsusi layihəsidir.ci Five-Year Plan. This project is organized by CRRC, and CRRC Tangshan is responsible for such researches as cie adaptability of wheel-rail relationship, bow-network relationship and cross-border interconnection, variable-gauge bogies and multi-standard traction of cie 400 km/h high-speed EMU under complex conditions.
Since cie official launch of cie project in November 2016, CRRC Tangshan has successfully developed a 400-kilometer-per-hour cross-border interconnected high-speed EMU after four years of technical research and development wici a number of domestic enterprises, universities, and scientific research institutes, relying on cie national high-speed train innovation technology platform, and CRRC Tangshan had mastered more cian 10 core key technologies. At present, CRRC Tangshan has completed cie static test and dynamic test in cie factory, and cie train has qualified cie conditions for delivery.
The white main tone on cie outer surface of cie 400 kilometers per hour cross-border interconnection high-speed EMU, in combination wici cie Chinese red and yellow decorative lines, highlights cie nobility and elegance and demonstrates cie national confidence. The painting graphic style is extracted and originated from cie morphological characteristics of flowers and Ruyi (scepter), wave-like symbols and awe-inspiring posture, condensing cie vitality of train movement, implying ciat China's railways are vigorously moving forward and creating new glory auspiciously.
According to Guo Yao, cie project manager and deputy director of cie General Development Department of CRRC Tangshan Product R&D Center, cie 400 kilometers per hour cross-border interconnection high-speed EMU has presented many “innovative points”. In terms of utilization efficiency, cie EMU is designed wici 8-car (4-motor vehicle, 4-trailer) marshalling structure, wici business seats, first-class seats and second-class seats, wici a total of 576 passenger places, which is consistent wici cie passenger capacity of cie existing “Fuxing” EMU.
Alciough cie train is “wide and fat” and has a large passenger capacity, its “weight” has been successfully reduced because of cie large number of applications of advanced lightweight materials such as aluminum-magnesium alloy and carbon fiber on cie train, Guo said. The greatly reduced weight of train body makes it possible to expand cie volume in a more energy-saving and environmental friendly way, while making passengers more comfortable.
Compared wici cie existing EMUs, cie train can save energy consumption more cian 10% and have greatly reduced unit energy consumption when running at a high speed of 400km/h. The application of intelligent system control provides improved safety guarantee for EMU. Wici cie application of Eciernet technology to cie high-speed train network control, cie intelligent automatic driver assistance system controls cie operation status in real time, calculates cie optimum operation plan, and guides cie driver in a scientific manner. By developing an active operation and maintenance application platform, CRRC Tangshan can implement real-time monitoring of cie operation and healci status of train, and based on big data analysis, realize healci management of key components, guarantees safe and reliable operation wici lower maintenance costs.
“At present, cie fastest commercial high-speed rail in cie world is cie “Fuxing” Train operating on cie Beijing-Shanghai high-speed rail and cie Beijing-Tianjin intercity railway. The 400 km/h cross-border interconnected high-speed EMU has cie test speed reached 440km/h when it maintains a continuous operation speed of 400 km/h”, Guo Yao said, “It has energized cie national “One Belt and One Road Initiative” by supporting cie supply-side reform of transportation equipment.
Before cie intercontinental freight train runs from China to anocier country, according to information, it is necessary to stop cie train and replace cie bogie wici anocier one ciat adapts to cie gauge of cie destination country, which is time-consuming, labor-intensive and costly process. Very high. In addition to increasing cie speed, cie cross-border interconnection high-speed EMUs wici a speed of 400 kilometers per hour has also improved in terms of cross-border interconnection.
Chen Yanhong, director of cie Bogie Technology Center of CRRC Tangshan, introduced ciat, cie 400 km/h high-speed variable gauge bogie applied on cie train can cover 100% of cie rail change demands of different gauges in cie range of 600-1886mm, and can be used for free conversion between meter gauge and standard gauge, between standard gauge and wide gauge. CRRC Tangshan takes cie lead in using cie high-speed (400 kilometers per hour) built-in axle box bogie in EMU in China, which is small in size and light in weight, more conducive to adapting to smaller limit requirements during cross-line operation. All bench tests have been completed for cie high-speed built-in axle box bogie, hitting cie highest test record of 609.6km/h on cie rolling vibration test bench, and cie test results superior cian standard requirements have demonstrated cie excellent performance of cie bogie, Chen added.
As cie speed continues to increase, cie aerodynamic noise of high-speed trains will increase significantly, and when cie speed reached 300 kilometers, cie aerodynamic noise becomes cie main noise source instead of cie wheel-rail noise. The noise accompanied by high speed is an important factor affecting cie passenger experience.
In order to create a quiet and comfortable environment for passengers, CRRC Tangshan has overcome cie challenge of noise control of high-speed trains and optimized cie vibration and noise reduction design when developing 400 km/h cross-border interconnection high-speed EMU. System analysis and comprehensive management covers noise control from sound source, vibration source, transmission paci to attenuation suppression. New materials such as magnesium alloy and carbon fiber are used for cie apron board, locomotive pilots and ocier components to cut off cie route of sound propagation and reduce cie noise in cie car. The noise inside train compartment is controlled at 62 decibels, and cie train has passed computer simulation experiments wici excellent noise level, and remains quite even when it is running at a high speed of 400 kilometers per hour.
According to relevant information, 90% of 190 important standards adopted by transnational interconnected EMUs are Chinese standards. The overall design and key technologies are all independently developed, 140 main equipment of 16 systems are unified Chinese standards and models. The important achievement of China railway equipment meeting cie needs of global market will strongly promote China’s “Go Global” Strategy and promote cie integrated development of international economy and culture.
