摘　　要：弓网间的磨耗包括机械磨耗和电气磨耗,而且大部分同时伴随着这两种类型的磨耗。从地铁刚性接触悬挂布置、悬吊结构刚度以及弓网电接触等方面,分析弓网磨耗问题产生的原因。为有效改善弓网间的磨耗,提出相应的措施及建议:综合考虑整条线刚性接触网的布置,增加特殊区段悬吊结构的弹性,选择与接触网相匹配的受电弓,精心进行接触网施工和检修等。Pantograph-catenary abrasion includes mechanical abrasion and electrical abrasion,and they are often accompanied by each other.Considering the arrangement of metro rigid overhead catenary system,suspension structure rigidity and electrical contact between pantograph and overhead contact line etc,the paper analyzed the causes of pantograph-catenary abrasion and put forward some improvement measures and suggestions.
