摘要

为了将车辆的横向载荷均匀地分配到各个悬浮架模块上，目前中低速磁浮车辆均安装有导向机构。由于导向机构空间跨度大、运动范围大、磁浮车辆进出小半径曲线时导向机构承受的载荷较大，进而导致导向机构安装空间和重量较大。因此，研究导向机构对车辆运行的影响，对优化导向结构并进行轻量化设计至关重要。文章介绍了四悬浮架中低速磁浮车辆中导向机构的结构和存在问题，对比分析有无导向机构对车辆运行性能的影响；同时提出了一种导向机构的优化方案，可保证车辆在运行安全的前提下减小导向机构载荷。

Abstract

In order to evenly distribute the lateral load of the vehicle to each suspension frame module, the medium and low speed maglev vehicles are equipped with a guide mechanism. Due to the large space span, large range of motion and the large load on the guide mechanism when the maglev vehicle enters and leaves the small radius curve, the installation space and weight of the guide mechanism are large. Therefore, it is very important to study the influence of guiding mechanism on vehicle operation for optimizing guiding structure and lightweight design. The structure and existing problems of the guiding mechanism in the medium and low speed maglev vehicle with four suspension frames were introduced, and the influence with and without the guiding mechanism on the running performance of the vehicle were compared and analyzed. An optimization scheme of the guiding mechanism was put forward, which could reduce the load of the guiding mechanism on the premise of ensuring the safe operation of the vehicle.
