Abstract

The invention relates to the technical field of rail vehicle test equipment, and discloses a rail transit power cable fatigue test machine fixture which comprises a fixed end fixed on a test vibrationtable, a movable end corresponding to the fixed end and a driving system, wherein the fixed end comprises a supporting frame and a first connection assembly located above the supporting frame and used for being connected with a terminal of a cable to be verified; the movable end comprises at least one L-shaped sliding block and a base for being fixed on the test vibration table, the base is provided with a horizontal slide rail slidably connected with the at least one L-shaped sliding block, and a vertical portion of the L-shaped sliding block is provided with a second connection assembly forconnection with the cable to be verified; the driving system is used for driving the L-shaped sliding block to slide on a horizontal sliding groove. The fixture can test power cables of different types and different lengths, the synchronization is good, and the test result comparability is relatively strong.

Description

technical field [0001] The invention relates to the technical field of rail vehicle testing equipment, in particular to a fixture for a rail transit power cable fatigue testing machine. Background technique [0002] In order to ensure the safety of train operation, it is usually necessary to conduct reliability analysis and life prediction for the power transmission during locomotive operation. When the fatigue test life of the joint connection is tested, the corresponding fixture is usually designed. However, the current fatigue testing machine fixtures are usually only suitable for power cables of fixed models and fixed lengths. If the fatigue tests of power cables of different models and lengths are tested, the operation process is complicated, the synchronization is poor, and the test results are difficult to compare. Low efficiency and other issues. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention ...
