摘　　要：研究目的:走行机构作为气浮车的走行和转向机构,是实现车辆"悬浮、导向、牵引/制动"功能的最基本、最直接的机构,也是气浮车在轨道交通应用领域需要解决的关键技术之一。本文根据气悬浮列车有别于轮轨列车和磁悬浮列车的独有特征,对气悬浮列车的走行机构进行了概念设计。研究结论:(1)气悬浮列车采用"多单元串联"形式的走行机构,有利于列车的平面和竖曲线通过;(2)气悬浮列车走行机构主要由喷气机构、摇枕摆杆机构、牵引机构、导向机构、制动及紧急救援支撑装置等组成;(3)为了适应轨道不平顺及曲线超高顺坡形成的线路扭曲,气浮架纵梁与横梁之间采用弹性连接,气浮架与纵梁之间以及喷气嘴与纵梁之间采用弹性材料连接,与纵梁连接的喷气嘴不再是一个长条状整体,而是分割为数个单元的小喷气嘴;(4)本研究结果可供轨道交通新制式运输工具走行机构设计参考。Research purposes： As an important part of the air film train,the running gear has a basic function to achieve ＂ suspension,guidance,traction / braking＂,which is a key technical problem in rail transportation application.Based on the unique characteristics of the air film train which is distinguishing from the wheel- rail train and maglev train,the conceptual design of the air film train has been discussed in this paper. Research conclusions：（ 1） Air film train adopts a running gear in ＂ multi- unit in series＂ form,in order to facilitate the train passing the vertical and plane curve.（ 2） The running gear of air film train mainly makes up of air- jet mechanism,bolster the pendulum mechanism, traction mechanism, guiding mechanism, braking and emergency supporting device and so on.（ 3） In order to adapt to the track distortion as a result of track irregularities and superelevation slope,the longitudinal beam and the cross beam is connected by flexible material,so it is with the longitudinal beam and air- jet mechanism. The air- jet nozzle is divided into several small units instead of a long strip.（ 4） The research results can provide references for design of running gear in new rail transit system.
