摘要
本课程设计是绘制导线的应力弧垂曲线和安装曲线。通过查有关《规程》得到了我们所要求的气象区的气象条件以及导线的相关参数,再通过书上的公式我们求出导线的各类比载,用列表法求得临界档距,并判断有效临界档距和控制气象条件,以控制条件为已知状态,利用状态方程式计算不同档距、各种气象条件下架空线的应力和弧垂值,按一定的比例绘制出应力弧垂曲线和安装曲线。本课程设计的重点和难点内容是关于状态方程式的求解,要利用有关计算机方面的知识,但这并不能阻止我们完成这个设计,在和同学的共同努力下我们成功的完成这个课题。在这个课题的设计过程中我们遇到了许多问题,但是也能够在通力合作下解决它们,使我对知识的理解加深了。
