Research on the Adaptability of Catenary Engineering Computing System

研究目的:接触网工程计算是电气化铁路接触网施工中的重要环节。从二十世纪八十年代开始,德国等发达国家利用计算机技术研制了用于接触网施工计算的软件系统。近年来随着科学技术的不断发展,我国在这方面的研究也有了长足的进步。但由于受接触网系统标准化的程度、计算机操作系统的换代等因素影响,现有的接触网工程计算系统已不能适应多种不同技术条件下的应用需求,制约了施工作业效率的进一步提升,亟需对接触网工程计算系统的适应性展开系统性研究。研究结论:(1)研发的接触网工程结构计算的通用数学模型,可以解决目前国内主流装配结构、安装形式(含引进技术)的计算问题;(2)利用GDI+技术,可以实现结果模拟校验及实时测绘功能;(3)软件能在目前微软多种操作系统上安装运行;(4)可解决中心锚结、四跨、五跨以及分相锚段关节等特殊区段的精确计算问题;(5)为计算系统数据接口提供了系统化的解决方案;(6)该成果主要应用于国内新建、改建电气化铁路接触网安装作业施工计算。

Research purposes： Contact network engineering calculation is an important link in the construction of electrified railway contact network. From the beginning of the last century in the eighties, Germany and other developed countries have developed the software system for the construction calculation of the contact network using computer technology. In recent years, with the continuous development of science and technology, our country has made great progress in this area of research. But as a result of the catenary system standardization degree, computer operating system upgrades and other factors, the catenary engineering of existing computing system has been unable to meet different application requirements under different technical conditions, constraints to further improve the operation efficiency of the construction, it is urgent to contact network engineering computing system adaptability study. Research conclusions： （ 1 ） A general mathematical model for the calculation of the engineering structure of the contact network is developed, which can solve the problem of the calculation of the main assembly structure and installation form （including the imported technology） in China. （2） Using GDI ＋ technology, can be achieved simulation and real - time mapping function. （3） The software can be installed on the current operating system, such as Microsoft. （4） It can solve the problem of accurate calculation of center anchor span and five span, and phase anchor joint special section. （5） It can provide a systematic solution for the data interface of the computing system. （6） The results are mainly used in the construction of new and rebuilt electric railway contact network installation work.
