Xinhua News Agency, Chengdu, January 13 (Reporters Wu Xiaoying and Wang Di) On the morning of the 13th, a silver and black engineering prototype vehicle was driving slowly on the test line in Chengdu. This is the world’s first high temperature superconducting high speed magnetic levitation engineering prototype and test line, which is independently developed and designed by China, and its test line is officially launched. The design speed is 620 kilometers per hour, marking the completion of China’s HTS high-speed magnetic levitation engineering research from scratch. Some advances.
It is reported that the high-temperature, high-speed, superconducting magnetic levitation engineering prototype and test line project is located in the Key State Traction Power Laboratory of Southwest Jiaotong University. The verification section is 165 meters long. Joint research and development of Southwest Jiaotong University, CRRC, China Railway and other units have conducted joint research.
High-temperature superconducting magnetic levitation technology has the characteristics of self-suspension, self-steering and self-stabilization, which is suitable for future transportation by vacuum pipes. Theoretically, the high temperature superconducting magnetic levitation train is expected to exceed 1000 kilometers per hour in a low vacuum state.
Wu Shengquan, deputy general manager of CRRC Tangshan Locomotive and Rolling Stock Co., Ltd., said that high-temperature superconducting magnetic levitation technology uses the “fixation” effect of superconductors in the magnetic field to achieve levitation and guidance. . It has the advantages of no real-time control of the levitation guide and low resistance in the forward direction. One of the high-speed technical lines of maglev vehicles has wide application and development prospects.
The reporter saw that the front of the high-temperature high-speed superconducting magnetic levitation engineering car prototype adopts a streamlined design and is shaped like a bullet. Unlike the high speed rail that runs on the rails driven by the on-board power supply, the prototype car is suspended on a permanent magnet track with a linear motor in the middle of the track, and a device is installed superconducting levitation at the bottom of the car to replace the wheels.
According to Wu Zili, a senior engineer at Chengdu Southwest Jiaotong University Design and Research Institute Co., Ltd., the prototype adopts new technologies and new processes, such as a lightweight carbon fiber body, a type of low-resistance head and a high temperature, large charge superconducting magnetic levitation technology. The design speed is 620 kilometers per hour. It is expected to create a new record for the speed of land traffic in the atmospheric environment.
Deng Zigang, deputy director of Southwest Jiaotong University ultra-high-speed vacuum pipe maglev transportation research center, said the completion of the project is an important implementation step to promote the engineering of high-speed superconducting magnetic levitation technology. temperature, which can perform suspension, steering, Basic functions such as traction and braking, as well as joint debugging and joint testing of all system engineering, meet subsequent research and testing and lay the foundation for breakthrough long-term up to speed value greater than 1000 km / h.
