Pantograph/contact network coupling system running test bend and testing method thereof

Abstract

The present invention provides a pantograph / contact network coupling system running test bend and a testing method thereof, and belongs to the technical field of rail traffic bow net simulation test bends. A bottom part of a stand column and an upper surface of a bend base are fixed to form a frame of a gate shape. Flanges are disposed at both ends of a beam, and the beam is fixed with a sliding block in a middle part of a stand column by using a bolt. A locking seat is disposed at an outer side of the sliding block. A vertical motion actuator is disposed in the middle of a bottom part of thebeam. A horizontal motion actuator is disposed at each side of the vertical motion actuator. A force sensor is disposed at a lower end of the vertical motion actuator, and contacts a pantograph bow ofa pantograph. A bottom rack of the pantograph is fixed with an upper surface of a six-degree-of-freedom platform. The six-degree-of-freedom platform is used for implementing a vibration signal of a spatial motion attitude at a train top pantograph base. A D / A board card is used for converting a digital signal into a simulation signal. A hydraulic servo control system is used for inverting a pantograph base motion attitude, and predicting a contact linear displacement of a point at which the pantograph contacts a contact network at a next moment.

Description

technical field [0001] The invention belongs to the technical field of rail transit pantograph-catenary simulation test bench. Background technique [0002] In the electrified railway line, the power supply for vehicle operation and auxiliary equipment lights on the vehicle is obtained through the contact between the pantograph above the vehicle roof and the catenary above the line to take current. A good contact state can ensure stable current reception, while a bad In the contact state, arcing and electric sparks will be generated. In severe cases, the contact wire will be burned. In extreme cases, the pantograph or catenary will be damaged and cause major operational accidents. Therefore, a good contact state is to ensure the safe operation of the vehicle. key. The operating performance and health status of the pantograph and catenary can directly affect the power supply stability of the traction power supply system. Pantograph-catenary dynamic contact force is a key pa...
