摘要

弓网接触压力是弓网系统动态性能的核心参数

弓网电动力是弓网接触压力的一部分

而国内外缺乏关于弓网电动力的研究。因此分析了由弓网电接触引起的弓网接触电动力的机理

考虑了弓网结构及受电弓运动的影响

然后结合滑板–接触线的电气机械材料及几何特性

利用有限元方法分析了拉出值、牵引电流和接触线往复运动等因素对弓网接触电动力的影响

并论证了模型的有效性。结果表明:牵引电流是弓网接触电动力的主导因素

接触线拉出值和接触线往复运动对弓网接触电动力的影响很小;牵引电流I=4kA时

弓网接触电动力可达10.3 N

为弓网接触压力的10%以上;弓网接触电动力随着弓网接触压力提升而减小。

Abstract

The pantograph-catenary contact force（PCF） is a key parameter in dynamic performances of pantograph-catenary system

and the pantograph-catenary electro-dynamic contact force（PECF） is one part of PCF. Therefore

we analyzed the mechanism of PECF which is induced by pantograph-catenary contact. Based on the structure of pantograph-catenary and pantograph-catenary interaction

a PECF model was established. Considering the electric

mechanical

material and contour characteristics of strip and contact line

the variations of PECF were obtained

and its effectiveness was indirectly proved by classic Holm force theory. The results show that the zigzag value and reciprocation of catenary wire contribute little to PECF

and the traction current is the dominant factor of PECF. While the traction current is 4 kA

PECF reaches 10.3 N

which is more than 10% of PCF. Moreover

the PECF will increase when the PCF declines.
