Abstract Research purposes:To ensure that the high-speed maglev train has good running safety and comfort when running on long trunk lines, the track smoothness has extremely strict requirements. Therefore, it is necessary to separate the track structure that provides high smoothness from the bridge that provides support, to significantly reduce the manufacturing and construction difficulties. It is necessary to study the new track structure form, and then develop the new fine adjustment technology based on the characteristics of the track structure, so as to provide an effective way to achieve and maintain the high smoothness of the track system.
Research conclusions:(1) A new type of high-speed maglev track structure with track plates laid on the laminated beam or box beam is proposed, which only needs to ensure the high-precision manufacturing and fine adjustment of the track plates, thus avoiding the overall high-precision requirements of the track beam. (2) A set of new track structure fine adjustment system of high-speed maglev has been formed. It mainly includes magnetic suction fine adjustment prism, fine adjustment software to realize the conversion between the positioning point of track plate and the spatial position of fine adjustment prism, fine adjustment claw integrating three-dimensional fine adjustment and fixing of track plate, connection and support device between fine adjustment claw, track plate and bearing beam. It can solve the key problems of realizing high-speed maglev fine adjustment engineering. (3) The research results of the new track fine adjustment technology of high-speed maglev can provide reference for the construction and operation of high-speed maglev project.
