摘　　要：我国电气化铁路建设快速发展,对接触网悬挂的安装要求越来越高,其中吊弦长度计算是接触网悬挂设计的重中之重。本文针对高速铁路接触网锚段关节处吊弦长度的计算进行分析,采用曲线拟合方程推导出各吊弦点处接触线的高度差,进而有效提高吊弦长度的计算精度,为实现高品质弓网关系提供坚实基础。The rapid development of railway electrification in China requires higher standard for installation of OCS suspension,among which,the dropper length calculation is the most important point for design of OCS suspension.The paper analyzes the calculation of lengths of droppers in overlap section of OCS for high speed railway,derives the height differences of contact wires at droppers by means of fitting curve equation,and the calculation accuracy of dropper length is improved,providing solid foundations for realizing of high quality pantograph-catenary interactions.
