接触网平面设计-本科毕业论文

摘要

随着社会和经济技术的发展，电气化铁路的发展也越来越迅速。我国对能够适用于电气化铁路的接触网也提出了相关的要求。本设计的目的是完成嘉峪关车站接触网平面设计，同时按要求绘制接触网设备装配图和平面图。

首先对设计地区的气象条件资料进行收集，根据铁路目标速度对线索材料进行了选择，再确定其悬挂类型。根据气象条件及线索材料计算负载。其次，根据最大受风偏移计算得到最大跨距；根据规程规定的锚段长度选择锚段，使其张力差要满足要求。然后，对硬横跨进行分析选择。考虑到接触网将来可能的改进及预留，根据计算结果对接触网进行了相应的调整，以使本设计满足电气化铁路的技术要求。最后在上述原理的基础上，对嘉峪关车站接触网进行CAD平面设计，并对具有代表性的支柱进行了容量的校验计算。在接触网平面图的表格栏里对地质情况、支柱类型、安装图号、侧面限界等进行相应的说明。

本论文以接触网的基本技术原理为核心，以实际线路状况为依据，对嘉峪关车站的接触网布置进行了平面设计，基本满足电气化铁路的技术要求。

Abstract

With the development of social and economical technology, the electrified railway is developing more and more rapidly. Our country also makes a related request for catenary of electrified railway. This design is intended to complete graphic design of catenary for Jiayuguan station, and to draw its device assembly drawing and graphic draft.

Firstly, the suspension was selected after the Jiayuguan weather condition information was collected and clue material was sift. The load was calculated according to weather condition and clue material. Secondly, the maximum outreach is obtained from the wind shift. Anchoring section is chosen according to specified anchoring section to satisfy tension difference. Then, portal structure was analyzed.The thesis considering the improvement and reserve in the future of catenary carries out some corresponding adjustments for the design of catenary according to the result of calculation, so that the design could be contented with the technical requirements of the electrified railway. Finally, on the basis of the above principle, this thesis concentrated on the graphic design of Jiayuguan station with CAD, also conducted check computation for typical capacity of the pillars. Graphic design of catenary in the form column on the pillar type, geology, side gauge, install the corresponding figure number and other instructions.

Based on the basic technical principle of catenary and according to the actual railway condition, this thesis completed graphic design of catenary for Jiayuguan station, which could met the basic technological demand of electrified railway.

Key Words: Catenary, Station, Graphic design
