Subway of new generation carbon fiber " CETROVO " appear on technology of traffic of Berlin international orbit to exhibit.
Car window is to touch accuse to display screen, resemble exceeding the flat computer of big edition.
On September 18, the technology of traffic of Berlin international orbit that holds in Germany is exhibited on, in joint-stock company of car all directions released car of subway of new generation carbon fiber formally " CETROVO " . It is reported, this car is our country is brand-new generation subway, use development of a large number of advanced new material, new technology, traditional subway is compared to come true to upgrade in the round in the respect such as energy-saving environmental protection, comfortable, intelligence, it is the latest technology achievement of domain of our country subway, representing the technical tide of prospective subway train.
Carbon fiber material is qualitative truckload decrease heavy 13%
The photograph is more traditional the subway, the characteristic with the oldest car of new generation subway is lighter, more energy-saving. Light quantify, reduce oneself weight as far as possible namely, it is a subway car implementation is energy-saving main avenue.
Assistant chief engineer of joint-stock company of all directions of the car in occupying is fourth three introductions, car of new generation subway uses advanced carbon fiber technology, all use carbon fiber composite material cabin of structural frame of bodywork, bogie, cab, equipment and equipment airframe to make. "The application of carbon fiber new material can make car comes true considerably ' thin body ' . " fourth three say, with use the phase of traditional metal stuff such as steel, aluminium alloy to compare, cabin of the bodywork of car of subway of new generation carbon fiber, cab, equipment is decreased respectively weigh 30% above, bogie structural frame is decreased heavy 40% , truckload decrease heft 13% .
"Although material of metal of prep above tradition wants on production cost, but carbon fiber composite material is quantified more gently, energy-saving advantage is clear, and have be able to bear or endure exceedingly goodly fatigue, corrosion resistance can. " fourth three say, after automobile body becomes light, also reduced the harm to circuit.
According to calculating, car of new generation subway but integrated and energy-saving 15% above.
15 kilometers still can run after cutting off the power
The photograph is more traditional the subway, car of new generation subway gets used to environment of worse climate geography, can be in high temperature is high wet, - move below the complex environment such as 2500 meters 40 ℃ Gao Han, high height above sea level.
In the meantime, in the light of subway route the turn much, radius is small, car equips in bogie first active and radial system, when monitoring car to enter curved talk, can control wheel pair to lie travel of curvilinear radial position. The curve that improved train greatly so passes property, can get used to ditty line better, the smallest turn radius can amount to 80 meters, subway of Yuan Chaochuan all, wheel wear and tear also is reduced considerably, managing maintain cost.
Car is in when doing not have exterior power supply also can travel. Because laded store can system -- dynamical accumulator, can offer drawing motivation travel for car 15 kilometers. When should producing power supply breakdown but lash-up moves, convenient also and online road and car paragraph " the area that do not have report " travel.
Car window is exceed big edition " Pad "
Apply contemporary intelligence to change a technology, car of new generation subway or high intelligence change " wisdom train " . Car window changes to be touched as accuse to display screen, become what can transmit information of all sorts of graph article video " demon window " . Be equivalent to exceeding big edition " Pad " , the passenger needs to feel car window with finger only, can see the news, webpage that browse on car window, buy a ticket, brush video, watch TV living broadcast to wait, get all sorts of services conveniently. The mirror in railroad car, also become can touch accuse, can get online " demon lens " . The air conditioning in railroad car, can decide proper temperature and humidity automatically according to weather and clad index, feeling allowing system is cozier. Lighting system but at any time the radial environment of witting railroad car, self-correcting brightness and colour temperature. Still have hold of multimedia curved surface, from clean seat, deploy for audition deformity passenger aid listen to a system... the passenger that intelligence changes serves a system, will bring the brand-new experience that take a car.
The highest moving speed per hour of car of new generation subway can amount to 140 kilometers, faster than traditional subway. Use unmanned road-sense, train is started from hair car add decelerate, stop door of station, switch, answer a library to wait for the whole process that run to all be full automatic drive.
Apply safeguard also more intelligence. Appear in moving road unusual when, but automatic early-warning and safeguard remotely. Next, car of subway of new generation carbon fiber will have running test, begin circuit to try move.
■ new technology " 2+N " automobile body of agile organizing into groups can grow but short
Compare with traditional subway photograph, car of new generation subway has stronger applicability, in operation textural more agile, can get used to more complex moving environment.
Current, the subway car of our country is fixed organizing into groups, the division number of railroad car is immutable. Car of new generation subway was developed first " agile organizing into groups " function, train is unit of the smallest organizing into groups with 2, can come true according to operation demand " 2+N " the division is flexible organizing into groups, match to the random inside 12 limits in 2 railroad car, and finish " change personally " need to be less than 5 minutes only.
According to introducing, amount of passenger flow of fastigium of subway morning and evening is large, flow of guest of Ping Feng period is little, change according to passenger flow agile organizing into groups, large organizing into groups is used in fastigium, ping Feng period uses small organizing into groups, can come true so with most means operation of economy, managing specific power consumption, reduce operation cost, also benefit sends car density at increasing, raise service level.
Pensile intelligence is adjusted
Car " run firmlier "
Subway car uses new generation to be decreased advancedly brace up fall technology of a confusion of voices, by sit up more comfortable. When train moves, because track is wrong suitable meeting causes railroad car vibration, the pensile system that should go up through bogie will decrease brace up. The pensile system of traditional subway is not adjustable, call passive suspension. Car of new generation subway uses completely active and pensile technology first, in travel road, when railroad car produces vibration, can explore immediately, undertake to the damp of pensile system trends is adjusted, make pensile system hour is decreased at first-rate brace up condition, make thereby subway car " run firmlier " . Sit inside railroad car to also can feel quieter apparently at the same time. Optimized fall design of a confusion of voices, when train moves, passenger compartment noise only 68 decibel, reduced 3 decibel above than traditional subway.
According to introducing, as tall iron train, car of new generation subway still undertook air-tightness is designed, use sealed bodywork first, the passenger is in when taking, because wave motion of force of car internal pressure causes ear film,won't have oppressive feeling.
