Abstract

Under condition for simulating vibration of vehicle body and dynamic action of contact line, the method carries out testing contact pressure between pantograph and bow net as well as dynamic change regulation between pantograph and contact wire. At different speed, and different operating condition of contact line, under dynamic coupling state between pantograph and contact line, the method obtains dynamic change regulation between contact pressure of bow net and vertical displacement of contact point so as to be able to estimate quality of pantograph for receiving current.

Description

Technical field

[0001] The invention relates to a pantograph-catenary simulation test method and a special device thereof for testing the dynamic performance of an electric locomotive pantograph and a power supply catenary in a coupled operation state. Background technique

[0002] The electric locomotive pantograph is the key component of the locomotive and the only way for the grid to transmit electric energy to the electric locomotive. The dynamic performance of the pantograph has a great influence on the safe operation of the electric locomotive. From the perspective of pantograph-catenary design research and product performance measurement, it is very necessary to simulate and measure pantograph-catenary vibration during pantograph operation. The dynamic performance of the pantograph is mainly manifested in the current receiving quality under the dynamic coupling operation state of the pantograph and the catenary. Usually, the pantograph-catenary contact pressure and t...
