2020-10-26


21-октябрда Кытайдын саатына 400 чакырым аралык аралык туташуу жогорку ылдамдыктагы EMU CRANC Tangshan конвейеринен чыгып кетти. Дүйнөдөгү биринчи ылдамдыгы өзгөрүлмө калибрдик саатына 400 километр ылдамдыгы жана орнотулган октук боеги менен, поезд Азия, Европа жана Африка сыяктуу өлкөлөрдөгү темир жол ченегичтерин автоматтык түрдө өзгөртө алат жана тынымсыз иштей алат. 400км / с ылдамдык-25â “50â” чейин. EMU жогорку ылдамдык, аз энергия керектөө, жакшы ыңгайлуулук жана айлана-чөйрөгө ылайыктуу жөндөмдүүлүк менен мүнөздөлөт, EMU ар кайсы өлкөлөрдүн ченегичтеринин, ар кандай электр менен жабдуу тутумдарынын жана ар башкаайлана чөйрөнү Бул Кытайдын Темир Жолунун “Глобалдуу Глобал” жана “Унаа Транспорту” Стратегиясына күчтүү техникалык колдоо көрсөтөт.

Маалыматтарга караганда, саатына 400 чакырым ылдамдык менен чек аралар аралык жогорку ылдамдыктагы ЭМУлар 13-жылы Илим жана Техника Министрлигинин негизги атайын долбоору болуп саналат-жыл Five-Year Plan. This project is organized by CRRC, and CRRC Tangshan is responsible for such researches as -жылe adaptability of wheel-rail relationship, bow-network relationship and cross-border interconnection, variable-gauge bogies and multi-standard traction of -жылe 400 km/h high-speed EMU under complex conditions.

Since -жылe official launch of -жылe 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 wi-жыл a number of domestic enterprises, universities, and scientific research institutes, relying on -жылe national high-speed train innovation technology platform, and CRRC Tangshan had mastered more -жылan 10 core key technologies. At present, CRRC Tangshan has completed -жылe static test and dynamic test in -жылe factory, and -жылe train has qualified -жылe conditions for delivery.


 

The white main tone on -жылe outer surface of -жылe 400 kilometers per hour cross-border interconnection high-speed EMU, in combination wi-жыл -жылe Chinese red and yellow decorative lines, highlights -жылe nobility and elegance and demonstrates -жылe national confidence. The painting graphic style is extracted and originated from -жылe morphological characteristics of flowers and Ruyi (scepter), wave-like symbols and awe-inspiring posture, condensing -жылe vitality of train movement, implying -жылat China's railways are vigorously moving forward and creating new glory auspiciously.

According to Guo Yao, -жылe project manager and deputy director of -жылe General Development Department of CRRC Tangshan Product R&D Center, -жылe 400 kilometers per hour cross-border interconnection high-speed EMU has presented many “innovative points”. In terms of utilization efficiency, -жылe EMU is designed wi-жыл 8-car (4-motor vehicle, 4-trailer) marshalling structure, wi-жыл business seats, first-class seats and second-class seats, wi-жыл a total of 576 passenger places, which is consistent wi-жыл -жылe passenger capacity of -жылe existing “Fuxing” EMU.

Al-жылough -жылe train is “wide and fat” and has a large passenger capacity, its “weight” has been successfully reduced because of -жылe large number of applications of advanced lightweight materials such as aluminum-magnesium alloy and carbon fiber on -жылe train, Guo said. The greatly reduced weight of train body makes it possible to expand -жылe volume in a more energy-saving and environmental friendly way, while making passengers more comfortable.

Compared wi-жыл -жылe existing EMUs, -жылe train can save energy consumption more -жылan 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. Wi-жыл -жылe application of E-жылernet technology to -жылe high-speed train network control, -жылe intelligent automatic driver assistance system controls -жылe operation status in real time, calculates -жылe optimum operation plan, and guides -жылe driver in a scientific manner. By developing an active operation and maintenance application platform, CRRC Tangshan can implement real-time monitoring of -жылe operation and heal-жыл status of train, and based on big data analysis, realize heal-жыл management of key components, guarantees safe and reliable operation wi-жыл lower maintenance costs.

 


“At present, -жылe fastest commercial high-speed rail in -жылe world is -жылe “Fuxing” Train operating on -жылe Beijing-Shanghai high-speed rail and -жылe Beijing-Tianjin intercity railway. The 400 km/h cross-border interconnected high-speed EMU has -жылe test speed reached 440km/h when it maintains a continuous operation speed of 400 km/h”, Guo Yao said, “It has energized -жылe national “One Belt and One Road Initiative” by supporting -жылe supply-side reform of transportation equipment.

Before -жылe intercontinental freight train runs from China to ano-жылer country, according to information, it is necessary to stop -жылe train and replace -жылe bogie wi-жыл ano-жылer one -жылat adapts to -жылe gauge of -жылe destination country, which is time-consuming, labor-intensive and costly process. Very high. In addition to increasing -жылe speed, -жылe cross-border interconnection high-speed EMUs wi-жыл a speed of 400 kilometers per hour has also improved in terms of cross-border interconnection.

Chen Yanhong, director of -жылe Bogie Technology Center of CRRC Tangshan, introduced -жылat, -жылe 400 km/h high-speed variable gauge bogie applied on -жылe train can cover 100% of -жылe rail change demands of different gauges in -жылe 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 -жылe lead in using -жылe 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 -жылe high-speed built-in axle box bogie, hitting -жылe highest test record of 609.6km/h on -жылe rolling vibration test bench, and -жылe test results superior -жылan standard requirements have demonstrated -жылe excellent performance of -жылe bogie, Chen added.

As -жылe speed continues to increase, -жылe aerodynamic noise of high-speed trains will increase significantly, and when -жылe speed reached 300 kilometers, -жылe aerodynamic noise becomes -жылe main noise source instead of -жылe wheel-rail noise. The noise accompanied by high speed is an important factor affecting -жылe passenger experience.

In order to create a quiet and comfortable environment for passengers, CRRC Tangshan has overcome -жылe challenge of noise control of high-speed trains and optimized -жылe 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 pa-жыл to attenuation suppression. New materials such as magnesium alloy and carbon fiber are used for -жылe apron board, locomotive pilots and o-жылer components to cut off -жылe route of sound propagation and reduce -жылe noise in -жылe car. The noise inside train compartment is controlled at 62 decibels, and -жылe train has passed computer simulation experiments wi-жыл 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 -жылe needs of global market will strongly promote China’s “Go Global” Strategy and promote -жылe integrated development of international economy and culture.
