Abstract： In order to solve the problem that the service life of pantograph-catenary system slide plate material is shortenedand theelectricalcontact performanceis reduced due to frictionand wear，the influenceof external transverse magnetic field on the frictionand wear characteristics of slide plate is studied through sliding electrical contact experiments，and the BP neural network prediction model based on Pelican optimization algorithm is established.The results show that the friction coefficient first increases and then decreases with the increase of magnetic field strength; when the sliding speed increases，the wear rate of the sliding plate increases first and then decreases with the magnetic field strength; when the contact current or contact pressre increases，the wear rate decreases with the increase of magnetic field strength.Appropriate magnetic field strength can reduce the spalling of carbon layer on the sliding plate，reduce the surface roughness and reduce the wear.The research results can provide an effective method for the performance optimization and life prediction of the pantograph catenarysystem slide plate material.
