摘要
基于悬链线方程建立地铁车辆跨接电缆数学模型,确立电缆长度计算方法;为简化计算过程,利用MATLAB/GUI(人机交互界面)开发设计可视化计算软件。并以北京地铁7号线车端108芯跨接电缆及直流DC 110 V母线跨接电缆为例,进行实例验证。计算过程简单直观,得到的计算值和实际值误差很小,从而验证了计算软件的可靠性。
Abstract According to the catenary equation, a mathematical model is established for subway jumper cable length calculation, in order to simplify the process of calculation, a visual computing software based on MATLAB/GUI is developed. Then, the 108 core jumper cable and DC 110 V jumper cable used for Beijing metro Line 7 are taken as the example to verify the feasibility of the calculation soft-ware, a very small error amount between the calculated value and the actual one is observed.
