Swing testing machine and swing testing method

Abstract

The invention provides a swing testing machine and a swing testing method. The swing testing machine mainly comprises a front-back swing table and a left-right swing table, wherein the front-back swing table is mutually in matched connection with a base through a horizontal guide rail and a rolling wheel and performs front-back horizontal reciprocating rectilinear movement relative to the base, and the left-right swing table is connected with the base through a swing rod and performs left-right swing reciprocating rectilinear movement relative to the base. When the swing testing machine is utilized to perform a swing test, only two ends of a test sample piece are required to be connected with the front-back swing table and the left-right swing table respectively, then the front-back swing table and the left-right swing table are started to move, and front-back swing testing and left-right swing testing can be performed respectively. Front-back relative movement and left-right relative movement between two adjacent compartments can be simulated by utilizing the swing testing machine and the swing testing method, card-end bridge joint connectors can be tested simultaneously, achievement of automatic testing is facilitated through a PLC, and testing efficiency and testing reliability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of swing testing of jumper connectors, in particular to a swing testing machine and a swing testing method for swing testing of jumper connectors at car ends. Background technique [0002] The car-end jumper connector is a key component of the electrical system of high-speed EMU, urban rail, and subway vehicles. The stability of the performance of the end jumper connector plays a key role in the electrical system of the vehicle. [0003] During the operation of high-speed EMUs, urban rail vehicles, subway vehicles, etc., there will inevitably be front and rear relative motions and left and right relative motions between two adjacent carriages. When the locomotive is running, the car-end jumper connector must be able to stably and reliably withstand the sway caused by the relative movement between the carriages back and forth and the relative movement between the left and right, so as to ensure the safety of...

AI Technical Summary

Problems solved by technology

However, the current reliability test for the car-end jumper connector is usually to simulate the front and rear swing and left-right swing separately, resulting in low test efficiency, increased test cost, and reduced test reliability, which cannot meet the needs of the car-end jumper connector. High-efficiency, high-reliability test requirements
