接触网安装曲线及张力差曲线绘制的新方法

The New Method of Draw the Installing Curve and Tension Difference Curve in Catenary Design

采用ＴＵＲＢＯＣ２．０作为工具软件，编写了一个通用曲线的绘图程序。用户只需在菜单提示下，输入欲绘制的曲线的必要参数，即悬挂类型，悬挂参数，气象条件，程序就可以自动绘出相应的安装曲线或张力差曲线，该软件较好的解决了过去安装曲线及张力差曲线的计算中数据多，计算量大，易出错，繁琐等问题，提高了计算精度，并使安装曲线及张力差曲线的绘制方法趋于简单化和系统化。

In this paper,we develop a new method to draw the installing curve and intension dif-ference curve,It is the general installing curve program which is developed by Turbo C 2.0Language。Users can only input some essential parameters of the curve that they want todraw, such as suspension type, weather condition and line parameters,and the programwould draw its curve automatically.The program solves many difficult problems in the cal-culation of installing curve, such as mass data,heavy calculation,easy to make errors andetc,It raises the precision of calculation,and make it more convenient to draw the in-stalling curve and intension difference curve。
