- Abstract
High-speed maglev is a railway system that uses electromagnetic force to suspend vehicles on guide rails and uses linear motors to drive trains forward. Its suspension guide system, track beam system, traction control system, etc. are significantly different from High-speed wheel rails. This paper compares and analyzes the main technical parameters of high-speed maglev and high-speed wheel-rail from the aspects of line engineering, track engineering, bridge engineering, tunnel engineering, traction power supply engineering, operation control engineering, wireless communication engineering,etc,in order to provide reference for High-speed maglev engineering design and technical research direction. The research results show that the high-speed maglev has higher requirements on the accuracy and smoothness of the track structure,the frequency and deformation of the bridge and pressure tightness of the vehicles in the tunnel. the vertical natural vibration frequency of the bridge is required to be not less than 1. 1 times the train passing frequency in design; In addition, the High-speed maglev adopts ground control and fixed block mode, and only one train can run in a zone,and the coupling between the three subsystems of signal control, wireless communication and traction power supply is more closely. Higher requirements are put forward for the data transmission performance of vehicle-ground wireless communication. Traction positioning data delay requirement is not more than 5 ms.
