高速铁路接触线磨耗对接触网静态形状的影响

Influence on Static Shape of Overhead Contact System caused by Abrasion of Contact Wires of High Speed Railway

以京津城际的简单链形悬挂接触网为例具体研究接触线磨耗对接触网形状的影响。利用经典力学方法,推导出不同磨耗下接触线、承力索的静态形状计算方法,再计算不同磨耗下接触网的几何形状,通过对比有限元仿真结果,验证该计算方法的准确性。

This paper will study the effects of the friction of contact wire on the shape of catenary specifically, with the example of the corresponding simple stitched catenary in Beijing-Tianjin intercity transit. Firstly, use the classical mechanical methods to derive the calculation method of static shape of contact wire and load bearing rope in different attrition grades. Then calculate the geometry of catenary in different attrition grades. Finally, verify the correctness of this calculation method by comparing the finite element simulation results.
