跨座式单轨交通车桥振动研究综述

为了掌握跨座式单轨交通核心技术并进一步向全国推广,有必要对单轨车桥耦合振动进行深入研究。本文有针对性地以重庆地区跨座式单轨交通为例,在国内外相关的研究基础上,重点讨论了车辆、桥梁及轨道不平顺因素对跨座式单轨交通车桥耦合振动性能和车辆乘坐舒适性的影响的研究过程,旨在为单轨交通车桥振动研究提供一定参考。

Design of unballasted track bridges on Beijing——Tianjin intercity railway

Beijing-Tianjin intercity railway is the first newly-built passenger dedicated line with operating speed of 350 km/h in our country. During design,new ideas of bridge construction were carried out to ensure the requirements of safety,comfort and stability of the train under high-speed condition. At the same time,concepts of environmental adaptability,service to transportation and comprehensive benefits were observed. On the whole line,long-bridge schemes were adopted and the most advanced technologies of unballasted track were utilized on bridges,the length of which accounts for 87.7 % of the total line. The success of design and construction of the bridges on this rail has accumulated valuable experience for high-speed railway construction on a large scale in the future,and made it a marking,demonstrating,and model project to follow.

跨座式单轨列车走行轮胎磨损控制方法研究

为控制曲线工况下跨座式单轨列车走行轮胎的磨损,通过胎面橡胶摩擦特性试验提出修正的衰减指数摩擦模型,并采用有限元分析方法研究走行轮双胎的磨损特性,提出采用虚拟外倾方法控制走行轮胎磨损,采用构建曲面走行踏面的方法对虚拟外倾方法进行优化,研究表明:虚拟外倾方法使内、外走行轮胎总的摩擦功降低3.4%,但外侧走行轮胎的摩擦功偏度值增加了25%;相对于虚拟外倾方法,曲面走行踏面方法使走行轮胎总的摩擦功降低了12.9 J,外侧走行轮胎的摩擦功偏度值降低了5.17%,内侧走行轮胎的摩擦功偏度值降低了8.87%,有效降低了走行轮胎的磨损并改善了其磨损均匀分布程度。
