运用MATLAB绘制接触网下锚安装曲线

Drawing Anchor Curve under Catenary by Using Software MATLAB

接触网下锚安装曲线在施工中起着重要的指导意义,常见的下锚曲线有温度-坠砣距地面高度b值曲线和温度-棘轮绕绳圈数曲线。运用MATLAB软件,在程序中给出相关参数的值,用MATLAB编程语言写出某一温度下的b值和温度t的函数,或某一温度t和棘轮绕绳圈数的函数,则可运行得到函数的曲线图。对于一条电气化线路中多个不同的锚段长度,其安装曲线有几组,在程序中只需增加几个参数的取值,plot命令增加几个未知数,其余程序不做变动,便可绘制出几组曲线。

The anchor installation curve under the catenary plays an important guiding role in the construction. The common anchoring curve is the curve of b - value of the temperature - falling mound from the ground height and the temperature-ratchet winding curve. The value of the relevant parameters is given in the program by using MATLAB software, and a temperature b value and temperature t function, and a temperature t are written by using MATLAB programming language and the function of the curve can be get. The number of ratchet around the rope loop function, after the completion of the program to run. For an electrified line length of a number of different anchor section, the installation curve of several groups, with only a few parameter values are increased in the program, a few unknown number are added to plot command, the remaining procedures do not change, several sets of curves can be drawn.
