摘 要:轮轨式是目前轨道交通技术体系的主流,但由于空气阻力、轮轨黏着、运行噪声等问题的限制,在现有的技术水平下,难以经济地实现运营速度大幅度提高。为满足更高经济运行速度的需求,在利用磁悬浮技术减少轮轨摩擦、振动的基础上,构建低真空运行环境以减小空气阻力和噪声是未来更高速度轨道交通技术发展的重要方向。本文阐述了发展低真空管道高速磁悬浮系统的意义,研究了其技术特点、发展现状,分析了低真空管道高速磁悬浮系统的科学问题和关键技术,并提出了在国家层面立项研究、建设试验线和国家级实验室的政策建议。The wheel-rail type transit is the mainstream in the current rail transit technology system.However,due to the limitations of air resistance,wheel-rail adhesion,and operating noise,it is difficult to achieve economically any significant increase in the operation speed at the current technological level.To meet the demand for a higher economical operating speed,apart from the use of the magnetic levitation technique to reduce wheel-rail friction and vibration,construction of a low vacuum operating environment to reduce air resistance and noise is an important development direction for higher speed rail transit technology in the future.This paper expounds the significance of developing a high speed maglev system based on low vacuum pipelines,studies its technical characteristics and current situation,analyzes scientific problems and key technologies of this system,and puts forward relevant policy suggestions including project-setting research at the national level,building up test lines,and construction of national laboratories.
