People.com.cn Beijing 3 December, today, in the pilot section of Beijing Shanghai High-speed Rail Zaozhuang to Bengbu between the joint debugging and commissioning and integrated test, the domestic "harmony" new generation of high-speed EMUs CRH380A maximum operating speed of 486.1 kilometers per hour. This is following the September 28th Shanghai High-speed Rail commissioning record speed of 416.6 kilometers per hour, China High-speed Rail once again set a world speed railway operation test.
The Beijing Shanghai High-speed Rail through Beijing, Tianjin, Hebei, Shandong, Anhui, Jiangsu, Shanghai 7 provinces, connecting the Yangtze River Delta and Bohai Sea Economic Zone two, line from Beijing South Railway Station to ShangHai HongQiao Railway Station, railway length of 1318 kilometers, the entire total South Beijing, Tianjin west, South Nanjing, Shanghai Ji Nancy, Hongqiao 24 the station, is one of the world's first built line the longest mileage, the highest technical standards, the fastest high-speed railway, attract worldwide attention, the attention of the nation.
The Beijing Shanghai High-speed Rail Zaozhuang to Bengbu section of Beijing Shanghai High-speed Rail construction pilot section, shoulder the important task of demonstration and guide the entire building, is about 220 kilometers, the starting point for the Zaozhuang west station, via Xuzhou, Suzhou east station, finish at Bengbu station. Since the Beijing Shanghai High-speed Rail construction of all, the pilot construction has been at the forefront of the entire building, playing the "vanguard" role. In November 10, 2010, the Beijing Shanghai High-speed Rail pilot section to complete the traction power supply, communication, signal, power "Four Integration" construction, expansion joint debugging and commissioning and integrated test.
The main task of joint debugging and commissioning and integrated test is done under actual conditions matching debugging facilities. According to the Beijing Shanghai High-speed Rail pilot section joint debugging and commissioning and integrated test plan, test consists of a new generation of high-speed EMU test, ballastless track structure, the ground test aerodynamic effect test of 10 items. Through the joint debugging and commissioning and integrated test, system test more than 350 kilometers per hour operation condition of fixed facilities, mobile equipment safety, compatibility and applicability.
On the same day as the experiment task is composed of China independent research and development of domestic "harmony" CRH380A a new generation of high speed emu. The EMU is in the Ministry of Railways and the Ministry of science and technology under the unified organization and guidance, to "Chinese high-speed train innovative joint action plan" as a guide, by CSR Qingdao Sifang locomotive vehicle Limited by Share Ltd combined with the domestic first-class scientific research institutes and industry resources, the combination with combined way, through joint research development. The car is the world's fastest, the highest scientific and technological content of high speed train, the system innovation in the aspects of air strength, passenger interface, intelligent, reached the world advanced level. The car in September 28th in Shanghai High-speed Rail test run up to 416.6 kilometers per hour, currently in Shanghai High-speed Rail batch put into use.
According to experts, move in circles after the theory and practice of harmony, CRH380A a new generation of high speed train, through simulation, bench test, road test, test, analysis of the repeated demonstration, eventually leading speed, safety, comfort, energy saving and other technical indicators of the world. The overall design reflects the ten technology innovation: low resistance flow type, matching mode of vibration system with good tightness, high strength and tightness body, safe and reliable high-speed bogie, advanced noise control technology, the traction system with high performance, high speed double arch flow performance, braking system for safety and environmental protection, human nature the passenger interface and excellent intelligent performance.
Zaozhuang to Bengbu section of Beijing Shanghai High-speed Rail comprehensive test speed of 486.1 kilometers per hour, again refresh the world railway operation test of high speed, which is not only the construction of Beijing Shanghai High-speed Rail achieved another major achievements, but also is a significant achievement in technological innovation Chinese high-speed railway made, also is an important sign of an important witness the rapid development China high-speed railway and Chinese high-speed railway leading to the development trend of high speed railway.
Since the Beijing Shanghai High-speed Rail since November 15th along victory paved, has entered the "Four Integration" construction and building construction as the focus of the station construction stage, the project is in order to promote efficient. All the construction units and 10 more than the construction of army is to build a world-class high-speed rail as the goal, to lead the world trend of development of high speed railway has been appointed, to the Party of national the people responsible for the purpose, elaborate organization, careful construction, careful management, and strive to the Beijing Shanghai High-speed Rail construction has become the "world class operation speed, the world first-class quality, first-class technology and equipment, transport efficiency, world-class world-class management" quality engineering.
At present, the high-speed railway mileage has been put into operation in China reached 7531 kilometers, ranking first in the world. China has become the world's most complete high-speed rail system technology, integrated the strongest, longest operating mileage, the highest running speed, the largest country in the building
