摘要：
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. © 2018, High Voltage Engineering Editorial Department of CEPRI. All right reserved.
