| 摘 要： | 对预弛度接触线的简单链形接触悬挂,以2种抛物线单元为基础,给出只受自重影响下的简单链形接触悬挂静态形状计算流程,利用经典力学方法,推导出不同坐标系下接触线、承力索的静态形状。最后通过对比有限元仿真结果,验证该计算方法的准确性。应用该研究计算方法可对简单链形接触网进行吊弦预配计算,指导接触网的设计施工。

| Abstract: | The simple catenary has been built more and more in the main-lines and the metro.This paper concerns on calculating the static shape of pre-sag contact wire.First,based on the parabola element,the process of calculating the static shape under the influence of the gravitational field is given.The equations of the static shape of contact wire and messenger wire in different coordinate systems have been deduced.Finally,by comparing the finite element simulation results,the calculation method has been verified.In addition,it also can calculate the length of the drops. |
