摘要 研究目的:为了确保高速磁浮列车行驶在长大干线时具有良好的运行安全性及舒适性,轨道平顺性具有极为苛刻的要求,因此有必要将提供高平顺性的轨道结构和提供支承作用的桥梁相分离,以降低制造及施工难度。故需研究新型轨道结构形式,进而基于该磁浮轨道结构的特点来研发新型精调系统,从而为实现并保持轨道系统的高平顺性提供有效途径。
研究结论:(1)提出的在叠合梁或箱形梁上铺设轨道板的新型高速磁浮轨道结构,只需确保轨道板的高精度加工制造及精调,从而避免对轨道梁的整体高精度要求;(2)构建了一套高速磁浮新型轨道结构精调系统,主要包含磁吸式精调棱镜、实现轨道板定位点同精调棱镜空间位置进行转换的精调软件、集轨道板三维精调和下压固定于一体的精调爪、精调爪同轨道板及承重梁之间的连接支撑装置,可解决实现高速磁浮精调工程化的关键问题;(3)本文对高速磁浮新型轨道精调技术的研究成果,可为高速磁浮工程建设及运维提供参考和借鉴。

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.

Key words： high speed maglev new track structure fine adjustment system
