Abstract

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.
