摘要

随着城市轨道交通在全国的迅速发展，迫切需要改变原有的对城市轨道交通

供电线路进行检修或抢修的设备，为此，对陆轨两用车的研制将具有非常重要的

社会意义和可观的经济效益。

本文根据市场对城市轨道交通供电线路维修或抢修的需要，首先自行研制了

陆轨两用车的行走系统，该项技术目前在国内尚属技术空白。陆轨两用车的行走

系统实现了车辆在站台和轨道间快速转换的功能；且具有轨道和公路两套行走系

统及一套动力传动系统，实现了车辆在轨道和站台上自带动力分别行驶的需要。

整个行走系统在满足功能的基础上具有设计新颖、结构简单、安全可靠等优点。

为了在后续研究和生产物理样机之前对安装该行走系统的陆轨两用车的动力

学性能进行研究，本文以安装该行走系统的陆轨两用车为研究对象。首先介绍了

陆轨两用车行走系统的总体结构组成，并对本文进行仿真所采用的轨道行走系统

进行了较详细的分析和介绍。其次采用动力学仿真软件Adams/Rail对陆轨两用车建

立了完整的动力学仿真模型。然后以此模型为研究对象，针对不同线路工况下车

辆运行动力学性能进行了大量的时域内的仿真计算，主要包括车辆的蛇行运动稳

定性、车辆在直线运行时的Sperling平稳性指数、脱轨安全性和动态曲线通过性能

等。

通过对在轨道不平顺激励下陆轨两用车在直线及曲线上运行时的各种动力学

性能参数的分析，证明这些参数均符合GB5599-85

《铁道车辆动力学性能评定和试

验鉴定规范》。说明安装该行走系统的陆轨两用车在最高运营速度80Km/h范围内

具有良好的蛇行运行稳定性、乘坐舒适性、抗脱轨安全性和动态曲线通过性。从

而为后续的研究和物理样机的生产提供理论依据和技术参考。

Abstract

With the rapid development of urban orbit traffic, it is a matter of great urgency to

improve the equipments used for overhauling and repairing power supply lines for orbit

traffic in case of emergency. Therefore, the research into the roadrailer will have big

practical social and economic values.

Based on the market demand for the equipments of overhauling and emergency

repairing, firstly, the article focuses on the exploration and development of the

roadrailer mobility Systems, the technology of which will help to fill a vacancy in this

field domestically. The Systems enable the vehicles to transform quickly between

running at platform and in orbit. Composed of an orbit and a road mobility system and

also a power driven system, the Systems have allowed the cars with built-in powers to

run both at platform and in orbit respectively. Apart from all the powerful functions, the

Systems also boast of original design, simple structure and reliable safety.

For the sake of the further study of the Systems’ dynamic performance and the

future production of the model machine, the article targets at the research of the

roadrailer equipped with the Systems. In the first place, its structural composition is

introduced, and a simulation of the Systems is analyzed and presented in detail.

Secondly, a dynamic simulation software – Adams/Rail is adopted in modeling an

integrated dynamic simulation. After that, the model being the investigated subject, a

large number of simulation calculations containing all instances of vehicle motion

dynamic performances in certain time domain have been carried out, including

vehicular hunting motion stability, Sperling stationarity index in rectilinear motion,

digression safety and dynamic curve transit performance, etc..

Analyses of all kinds of dynamic performance parameters collected when the

roadrailer, inspired by irregular tracks, is in rectilinear and curvilinear motion arrive at

the sum-up: these parameters are definitely in accord with GB5599-85 Railway Vehicles

—Specification for Evaluation the Dynamic Performance and Accreditation Test.

Through the research comes the conclusion: the roadrailer with mobility systems, at or

below its maximal operation velocity of 80Km/h, are possessed of nicer hunting motion

stability, application comfort, anti-digression security and dynamic curve steering ability.

Therefore, academic basis and technological references have been proposed for the

further study and production of the model machine.

Key words: roadrailer, the running gear system, dynamics simulation

model, simulation calculations, dynamic performance
