Abstract

The invention discloses a bend fatigue testing mechanism for an on-satellite cable. The bend fatigue testing mechanism comprises a driving motor (1), a first connecting rod (2), a second connecting rod (3), a second cable fixing plate (4) and a first cable fixing plate (5), wherein the end part of a rocker located at the bottom of the second cable fixing plate (4) is rotatably connected with the end part of a rocker located at the bottom of the first cable fixing plate (5); the output shaft of the driving motor (1) is connected with one end of the first connecting rod (2); the other end of thefirst connecting rod (2) is rotatably connected with one end of the second connecting rod (3); the other end of the second connecting rod (3) is rotatably connected with the middle part of the rockerlocated at the bottom of the second cable fixing plate (4); the cable fixing plate (5) is stationary; and the driving motor (1) drives the first connecting rod (2) and thus drives the second connecting rod (3) and the second cable fixing plate (4) to perform crank-rocker movement. The bend fatigue testing mechanism of the invention aims to solve the problems of low reliability, complicated structure and incapable simultaneous multi-station testing and the like of the conventional testing methods.

Description

technical field [0001] The invention relates to a fatigue test mechanism. Background technique [0002] With the continuous improvement of satellite reliability indicators, more stringent requirements are put forward for the reliability of satellite cables, especially the cable reliability of the accessories of moving parts; In order to determine the degree of loss in the end, a test institution is needed to perform fatigue tests on the cables on the star. [0003] Patent CN1072260A "A Low-Frequency Fatigue Testing Machine", Patent CN2445318Y "Spring Fatigue Testing Machine", and Patent CN101957290A "A Fatigue Testing Machine and Its Method Suitable for Tensile Tests" respectively provide materials for metal materials, springs, etc. The design scheme of the tensile and compression fatigue test device, but it cannot be used to simulate the actual working conditions of the cable near the moving parts on the star; the patent CN103185851A "Flexible Cable Bending Life Test Devic...
