Research on Wear of Pantograph Slide Plate: A Review

doi:10.3901/JME.2025.08.193

Abstract

Abstract: Sliding contact between pantograph slide plate and contact wire is the primary mean to obtain electric energy during train operation. Its current receiving quality and reliability are directly related to train operation cost and safety. The relevant research and achievements on the friction and wear properties of pantograph slides in China and abroad in recent years are summarized, and the main wear mechanism of pantograph slides is expounded. The influence of key factors, such as relative sliding velocity, contact pressure, current-carrying condition, pantograph-catenary structure parameters and operation environment on wear are analyzed. The evolutionary history of pantograph slide material is listed, and various copper-based reinforcement materials widely used at present and their friction and wear properties are introduced. The analysis results show that under the development trend of high speed and heavy load of rail transit, the wear of pantograph slide plate has become an important content that cannot be ignored. At present, experimental research, material development and application systems have been formed to a certain extent, but there are still some problems that need further research by scholars at home and abroad, such as comprehensive evaluation method of pantograph slide plate wear, wear behavior of pantograph slide plate under extreme environmental conditions, active control technology and application of wear resistant materials.

Key words: pantograph slide plate, wear mechanism, friction and wear properties, arc erosion, copper-based reinforcing materials
