摘要
国内许多城市相继规划建设现代有轨电车系统项目,低地板技术的现代有轨电车造型新颖、舒适、转弯半径小的特点突出。轨道工程作为有轨电车中最重要组成系统之一,承受车辆的荷载,并引导车辆运行。针对有轨电车系统特点,阐述有轨电车主要技术标准差异性,结合目前国内外有轨电车轨道工程结构技术现状,重点分析轨道系统中钢轨形式、扣件、道岔、道床结构及减振降噪5个方面关键技术及相关问题,提出一些设计见解和建议。特别针对现代有轨电车维修困难和振动噪声问题,提出的轨道系统优化设计理念。
Many domestic cities plan to construct modern tram system project equipped with modern low floor vehicles characteristic of novelty, comfort and small turning radius. Track engineering is taken as the most important part of the tram system, which bears vehicle load and guides the vehicle operation. This paper focuses on tram system characteristics, addresses the differences in key main technical standards, and analyses the problems related to such key technologies as rails type, fastener, switch,track bed structure and vibration reduction with reference to current domestic and international tramway projects, and puts forward some design concepts and suggestions. Especially, the difficulties in modern tram maintenance and the problems of vibration and noise are discussed and optimization of design concepts is presented.
