On June 26th, a "China Standard" EMU with a local gold color and a design speed of 350 kilometers per hour slowly departed from China CRRC Changke Co., Ltd. (Changke) and opened to China Railway Science Research in Beijing. The hospital, after arriving on the same day, began a series of system type tests. Two months later, an operation test of 600,000 kilometers will be carried out, which is the final step for mass production.
In June 2013, the “China Standard†EMU project was officially launched. The China Railway Corporation requested that the “China Standard†EMU should integrate the advantages of various domestic EMUs and establish a unified technical standard system to realize the service function of EMUs. Use uniformity in maintenance.
This means that the two columns of standard EMUs developed by Changke and Qingdao Sifang Locomotive & Rolling Stock Co., Ltd. should be interconnected, reconnected, and complete the integration of 96 key components of 11 systems including traction, air conditioning and network. ——Typical type means that the joint parts of Changke and Sifang products can be interchanged, mainly to solve the problem of many operating vehicle platforms, mixed models, and inconvenient maintenance and repair. This is the first experience of the establishment of the “Joint Fleet†by two major domestic OEMs.
The important standards adopted by the “China Standard†EMUs cover all 13 major aspects of the EMU basics, car body, running gear, cab layout and equipment, and traction electrical. According to the person in charge of the long-distance passengers, the design of the standard EMU is based on the actual needs of China, such as continuous high-speed operation, long distance, high density of travel, large passenger capacity, high cold, snowy, plateau sand, coastal hot and humid. As well as the conditions of smog and catkins, the overall technical conditions of the EMU were put forward.
It is understood that the existing Harmony EMU will continue to produce and operate. Whether the word “Harmony†is applied on the standard EMU should be determined according to the situation.
â– Parameter
The main parameters of the "China Standard" EMU are as follows:
Running speed: 350km/h
Grouping form: 8 groups (4 moves and 4 drags)
Capacity: 556 people (10 seats in business, 28 seats in first class, 518 seats in second class)
Train length: about 209m
Body width: 3360mm
Roof height: 4050mm
â– Highlights
More spacious seat spacing
The majority of passengers are more concerned about the difference between the new off-line EMU and the existing Harmony EMU. It is understood that the "China Standard" EMUs use many new technologies in intelligence, safety, economy and operation.
Seat: The second-class seat spacing is uniformly adjusted to 1020mm, and the first-class seat is 1160mm, which is slightly larger than the existing Harmony EMU. The color of the seats is more distinctive, stylish and lively, and each seat is equipped with a socket.
Lighting: There are dozens of modes in the interior lighting. The brightness is from high to low. The light is warm to cold. Every passenger can use the reading light. The brightness and color temperature can be adjusted manually or automatically. The user-friendly design is more prominent.
Wi-Fi: The entire train's Wi-Fi network is fully covered, passengers can access the Internet at any time, and the journey is no longer lonely.
Safety: The anti-off-line device is loaded on the wheel rails so that the wheels will not leave the track line under extreme conditions.
Front: The front design absorbs the Phoenix element, and the design streamline reduces the drag by 5%, which means there is some safety redundancy in the case of speeds above 350 km/h. In the choice of the front, the long-term customer finally selected the current shape from 45 programs. The shape of the front end reflects the traditional Chinese culture. It draws inspiration from the elements such as Peking Opera and Dragon Totem, giving people a sense of fluidity and speed. It is a high-profile front design.
Maintenance: The “China Standard†EMU unified the maintenance standards of various motor train maintenance bases across the country, reducing costs for the operation department.
