MATLAB城轨列车节能坡设计方案研究
摘要：国家的快速发展和国民经济的日益提升以及我国城市人口在不断增长，使得城镇规模不断扩大，城市交通压力急剧增大，这是城市在发展过程中的一个重要问题，而为缓解城市交通压力，城市公共交通的发展变得十分迫切。其中，由于城市轨道交通具有快速、准时、运能大等优点，使其在缓解交通压力中的显著作用也越来越被人们所重视。但我们发现由于城市轨道交通运行区间短、起动制动频繁等特点造成的能量浪费十分巨大，针对这一现象，本文以城轨列车牵引计算和能耗计算的相关理论为出发点，通过对城轨列车进行受力分析、运行时分及距离解算、能耗计算等，利用MATLAB软件的GUI功能对不同节能坡线路类型进行计算结果的比较和分析，寻找节能坡节能基本特点，为逐步优化节能坡设计的方案提供较为有效的参考信息。68794

Study on Design Scheme of Energy Saving Slope in Urban Rail Transit
Abstract：With the rapid development of the country and the continuous growth of the national economy, the urban population of China is growing continuously, which makes the scale of the city expand and the urban traffic pressure increases rapidly. This is an important subject in the urban development process and alleviates the urban traffic pressure. The development of urban public transport has changed Very urgent. Among them, the urban rail transit with fast, punctual, large transport capacity advantage, can ease the important role of traffic pressure, by more and more attention. But we found that due to poor urban rail transit operations, frequent braking and other reasons, energy waste is very large. In view of this phenomenon, this paper based on the theory of urban rail transit vehicles traction calculation and energy consumption calculation, based on the results of different energy-saving slope line types, using MATLAB's GUI function to carry out the calculation and analysis software to find the basic characteristics of energy-saving slope energy saving and optimization Energy-efficient slope design, to provide more effective reference information.
