Rail transportation equipment manufacturing return rise should objectively look at China's high-speed rail achievement

Decades in global rail industry is facing opportunity of development, thankfully, China occupied the pioneer position in this industry. On October 26, 1978, comrade deng xiaoping during his visit to Japan Shinkansen "light - 81" super express train from Tokyo to culture the ancient city of Kyoto, Japan should be on the train please talk look and feel of the Shinkansen, Japan a reporter said: "there feel fast, people ran, we are in the car." For Japan's high-speed rail greiner and unwilling to lag behind the heart of the show quite clearly and do not break. The next morning, comrade deng xiaoping took kinki railway, express trains from Kyoto to visit nara. At the time, people mountain people sea of green skin of China railway car with Japan, the European high-speed rail on the bullet in the shape of a high-speed train gap seem so far away.

High-speed power forward at the speed of light

Idle away one's thirty years, accumulate through long-term research and development, through the leapfrog development to put into effect since the early 21st century, through the successful implementation of "the introduction of advanced technology, combined the design production, to build China brand" strategy, China's rapid growth for the world recognized as the top high iron power, in December 2010 the 7th world meeting, high-speed railway, then huawu, chief engineer of the ministry of railways to proudly announced to counterparts around the world, China is already the world's high-speed rail system, and the most latest technology integration ability of the strongest and longest running mileage, highest speed, the construction of the largest countries, is a series of tangible achievement gives him enough bottom spirit, also makes it very convincing counterparts around the world. Because since 1992, the international union of railways (UIC) launched since the high-speed rail assembly, all previous conference has been held in Europe, even recognized as a high-speed Shinkansen and completed operations for decades, Japan has failed to secure the qualification of the host country, at the end of 2010 the 7th world congress of high-speed railway in Beijing is the world's high-speed rail assembly for the first time in Europe, the move itself marks the international railway industry recognition of China's high-speed rail achievements:

- at the end of 2010, China's high-speed rail operating mileage of 8358 km, more than one-third of the world's high-speed rail operating range. As of 2011, has been put into operation in our country's high-speed train marshalling (8) a total of 786 standard column, which at 200 ~ 200 km/h speed level 250 column (short 290 columns, ChangBian 290 column), at speeds of up to 300 ~ 300 km/h speed level 350, speed 380 km/h speed level 133 columns (short columns, 40 ChangBian 93 column). With the increasing of number of high-speed trains, high-speed emu models gradually rich, introduced by the technology of single grouping marshalling (8), single use (car), single speed grades of four kinds of models, development so far, including length, sleeper, a variety of speed grade 12 models. According to the national "long-term railway network planning adjustment (2008)", in 2020, the national railway mileage to reach more than 120000 kilometers, FuXianLv and electrochemical rate above 50% and 60% respectively, the main busy trunk passenger line, the high speed railway passenger dedicated line will reach more than 16000 kilometers.

- Japanese high-speed trains in operation for the first time since 1964, after nearly 50 years of development, formed by overseas Japanese Shinkansen N700 series ICE with E5, French TGV and Germany represented by high-speed train technology, high-speed train operations from the original 210 kilometers to 320 kilometers per hour, one of Japan's Shinkansen, French TGV and German ICE operational speed of 300 km, 320 km and 300 km respectively. China has introduced a level 200 km of high-speed emu technology abroad, on the basis of the technology innovation through substantial increase running speed all the way, due to China's high-speed rail construction comprehensive startup process as a series of breaking and train speed world record of the process, for high speed emu, every promotion, about 30 kilometers per hour means a technological leap.

On June 24, 2008, the beijing-tianjin inter-city high-speed create record of 394.3 kilometers per hour. On September 29, 2010, domestic "harmony"

CRH380A trains in the shanghai-hangzhou high-speed railway commissioning when creating the new world record, 416.6 km per hour in just 40 minutes to run over 202 kilometers of distance between Shanghai - hangzhou. On December 3, 2010, the beijing-shanghai high-speed railway CRH380AL "harmony" emu commissioning run created the highest world record of 486.1 kilometers per hour.

With running speed advantages, and refreshes the definition of high speed railway in China. In accordance with internationally recognized standards, up to 200 km per hour can be referred to as the high-speed rail, but as a result of the running speed of more than 300 km high-speed line too much, too long, have to distinguish between, to run more than 300 kilometers per hour are called "high-speed rail", to run at 200 kilometers per hour above 300 km below the borrowed the name of the high speed train, referred to as the "bullet train".

- high quality, low cost competitive advantage. Compared with Europe, Japan, China's high-speed trains and related equipment manufacturing industry not only embodied in the most complete technical advantage, integrated ability is strongest, the highest running speed, but also in low cost and the construction efficiency. China's high-speed rail construction cost only a third to half of overseas counterparts, domestic high-speed rail general cost is 150 million yuan/km, Frankfurt, Germany - cologne line about 300 million yuan/km, opened in 2004 in South Korea's high cost is 250 million yuan/km railway base parts. The Vietnamese national assembly in June 2010 rejected the Japanese Shinkansen technology built in Hanoi - ho chi minh city rail line, the reason is that cost up to $56 billion, more than the Vietnam national strength under limit. If the technology in China, almost cost only half of the Shinkansen.

Rail transportation equipment manufacturing return rise

Along with the development of China's high-speed rail, the rail transportation equipment manufacturing industry also return rise, especially in CSR, China north car manufacturers, and implement the miraculous development. CSR was founded in 2000 as an enterprise turnover, resulting in a loss of 10.3 billion yuan, the turnover in 2010 has grown to more than $60 billion in profit enterprise, realizes the establishment at the beginning of the world, with strong international competitiveness of industry big goals.

In the aspect of technology innovation, the Chinese rail transportation equipment manufacturing industry is the result. Plateau of qinghai-tibet railway passenger car, 40 tons ore car axle load, and other products through the original innovation towards the high-end technology, created the global peers recognized achievements. For emu field, key technologies for the system, car body assembly technology, high-speed bogie technology, traction converter technology, traction control, traction motor, traction transformer, the braking system control technology, network technology, through the digestion, absorption, re-innovation and completely independent research and development, China's manufacturing and railway transport except there is gap in the braking system technology have made great progress in other areas, to the world, even the top:

Car body design and aerodynamic. Choice of high-speed emu is the independent design, independent made through wind tunnel test, without precedent in other countries. In late 2011, made the operation speed of 500 km emu like swords, also like chick, is unique. In these models have been put into production, the designers of railway equipment enterprises in our country also design a variety of new concept car, I only visited in February 2012, Qingdao CSR sifang see if factory have more than two digits, and models beyond normal appearance more imagine, some models appearance at first glance I feel more like fly fast jets, rather than Mercedes train on the ground.

High-speed rail. In China more than 350 km/h and independent research and development of high speed rail line with 60-42 of the single open rail.

Slab track. This is China's unique patented technology, is a Chinese pride and China's own research and development of Ⅲ type plate without a frantic jumble is one of the world's most advanced orbit.

The train control system. Germany is LZB Gao Tielie control system system, Japan is DS - ATC system, is French UM2000 TVM430 system, Europe is trying to promote GSM - R system, while China's high-speed rail the ZPW - 2000 + point + ATP train control system, and several other countries are not the same, belongs to the independent innovation.

Inverter. CSR independent research and development of photovoltaic inverter and GTI GTI - 250-250 had already passed the international certification, China south locomotive production of all models use is your inverter with charger.

Current transformer. CSR production inverter itself and its core components insulated gate bipolar transistor (InsulatedGateBipolarTransistor, IG pride BT), the chip design and manufacturing is completed; CNR also built their own insulated gate bipolar transistor packaging line.

Motor. When the initial introduction of high-speed rail technology to bundle motor technology, relying on strong leadership and "national game" conferred by the negotiation of powerful negotiating position, China's ministry of railways successfully broke the day, and the high-speed rail manufacturers attempt to blockade technology to continuously gaining high profits, forcing the other party to accept the transfer motor full set of technical terms, pay the price is also very economical. On the basis of introducing, CSR and CNR two high-speed rail equipment manufacturers in a relatively short time completed the digestion and absorption, all their production motor, and innovate in succession. 380 km/h emu, 500 km/h emu traction motor and transformer are independently developed, traction motor, traction transformer in CRH380A use to maintain equipment lightweight advantages at the same time, improves the system capacity by more than 30%.

In addition, do not belong to the high iron SUNGOLDPOWER products of CSR six axis 7200 kw high-power electric locomotive with only 6 months time to complete the design, production to the mass market, six axis high power electric locomotive 9600 kw and 9600 horsepower high-power diesel engine production, marked the CSR for a world-class locomotive equipment system integration suppliers.

Bearing and wheel. Current high-speed rail bearing and wheel localization rate is not high, but also has made a series of breakthroughs, for ready state. 160 km/h the following bearing is already full of domestic moving car models, more than 160 kilometers per hour models bearing has long been a source of imports, Harbin, wafangdian, luoyang bearing factory has been took out 350 KPH bearing samples at the end of 2010, a comprehensive breakthrough not far too. Maanshan has become the world's largest wheel manufacturer, high-speed rail and the train using the operational speed of 250 km and 350 km wheels has been developed in succession or put into use.

Overall, 2003 - at the end of 2010, China has applied for 1902 high-speed railway related technologies, including 1421 items have been authorized, 481 are accepted. By 2010, the high speed emu and high-power locomotive nine big core technologies and key components are CSR has realized the democracy in China.
