摘　　要：[目的]地铁系统存在接触线异常磨耗问题,有必要探讨弓网系统各重要数据与接触线磨耗厚度之间的数据关联程度。[方法]在实际线路进行弓网试验,测得动态接触力、列车运行速度、滑板垂向加速度、燃弧持续时间、母线电流、接触网拉出值及接触线磨耗厚度等实测数据,采用灰色关联法分析各因素对接触线磨耗厚度的影响占比。[结果及结论]列车运行速度直接影响接触线的磨耗厚度,其影响占比最大,动态接触力次之,其他因素按影响占比由大到小排序为燃弧持续时间、母线电流、接触网拉出值、滑板垂向加速度。[Objective] Since the metro system suffers from abnormal wear problem of contact wires,it is necessary to explore the data correlation degree between the key data of the pantograph catenary(PC) system and the contact line wear thickness.[Method] PC tests are conducted on the actual line,and measured data such as dynamic contact force,train running speed,vertical acceleration of the contact strip,arcing duration,bus current,catenary stagger value and contact wire wear thickness are obtained.The proportion of each factor′s contribution to the wear thickness of contact wire is analyzed by grey correlation method.[Result & Conclusion] The train running speed directly affects the wear thickness of the contact wire,and its influence accounts for the largest proportion,followed by the dynamic contact force.Other factors are ranked from large to small in terms of influence proportion as follows:arcing duration,bus current,catenary stagger value,and vertical acceleration of the contact strip.
