城市轨道交通车辆两种受电弓跟随性试验研究

为了研究城市轨道交通车辆不同驱动方式受电弓的跟随性,分别对气缸驱动弹簧受电弓和电推杆弹簧受电弓进行跟随性试验研究。试验结果表明:两种驱动方式受电弓的跟随性均随着弓网间相互作用频率的增大而变差;在受电弓自振频率附近均出现跟随性变弱的趋势;随着平均接触力增加,受电弓跟随性趋好;不同驱动方式受电弓在不同频率范围内的跟随性优劣不同。

Experimental Study of Pantograph Following Performance in Two Driving Modes for Urban Rail Transit Vehicle

In order to study the pantograph following per-formance in two diffferent driving modes for urban rail transit vehicle,the following performance experiments of cylinder spring pantograph and electrical putt spring panto-graph are studied respectively.The results show that in both cases,the pantograph following performance is deteriorated due to the increasing frequency of the gateway arch interac-ted with the pantograph catenary,and the weaker trend of pantograph following performance is influenced by the nat-ural frequencies in the vicinity of pantograph.With the av-erage increase of contact force,the pantograph following performance tends to become better.It is clear that differ-ent driving modes within different frequency ranges will di-rectly influence the pantograph following performance.
