Abstract

The invention provides a pantograph-OCS rolling electric contact experimental machine for experiment, which comprises a disc assembly and a rolling sliding plate mechanism, and is characterized in that the disc assembly comprises a disc rotating shaft and a disc arranged on the disc rotating shaft, the edge of the disc is provided with a groove, and a wire is embedded in the groove; the rolling sliding plate mechanism comprises two rolling sliding plate parts symmetrically arranged on the two sides of the disc rotating shaft, each rolling sliding plate part comprises a sliding rail and a sliding table assembly arranged on the sliding rail, and a rolling sliding plate is installed on each sliding table assembly. According to the experiment machine, a rolling electric contact friction pair is formed by a rolling sliding plate and a wire installed in a groove in the edge of a rotating disc, an alternating-current motor controls the rotating speed of the rotating disc to achieve setting of the movement speed, a linear motor serves as an actuator to conduct servo control over pressure loads, and according to the working condition to be simulated, the fluctuation change of the actual pressure between the pantograph-OCS is simulated.

Description

technical field [0001] The invention belongs to the technical field of rolling electric contact of electrified railway locomotives, in particular to a pantograph-catenary rolling electric contact testing machine for experiments. Background technique [0002] In electrified railways, the pantographs of electric locomotives obtain power from the catenary through sliding contacts. With the continuous increase of the running speed of electric locomotives, the hazards such as irregularity and hard points of catenary wires are amplified, pantograph-catenary vibrations are intensified, and the quality of current flow is deteriorated. The rolling electrical contact has technical characteristics such as high reliability, low friction, and low noise. If the rolling electrical contact is applied to the pantograph-catenary system, it is necessary to clarify the friction and wear mechanism and the flow quality characteristics of the rolling electrical contact mechanism. Exploring these ...
