Steel wire rope U-shape lock tool B (15) locking of wire cable clamp B (16), controls servo electric jar A (17) by computer
Move horizontally so that anti-fatigue steel cord (9) stress reaches to set fatigue load or deformation values；Servo is controlled by computer
Electric cylinder B (10) moves at vertical direction, until loading contacting between steel wire rope (14) and anti-fatigue steel cord (9)
Load value reaches setting value；
C () makes low-speed high-torque motor (1) obtain different alternating torsions by computer-controlled program regulation converter
Angle；Servo electric jar A (17) threaded rod, servo electric jar B (10) threaded rod is set by computer-controlled program
Alternating displacement amplitude, it is thus achieved that the fatigue load of anti-fatigue steel cord (9) and load steel wire rope (14) and tired steel wire
Dynamic alternation contact load between rope (9)；Turn on the power and pass to low-speed high-torque motor (1), converter, moment of torsion
Sensor (3), servo electric jar A (17), pulling force sensor (19), servo electric jar B (10), 2 D force sensor
(12), after energising, started low-speed high-torque motor (1), servo electric jar A (17) by computer program simultaneously, watch
Take electric cylinder B (10), simulate steel wire rope multiaxis fretting fatigue process；During steel wire rope multiaxis fretting fatigue, with change
Frequently device controls low-speed high-torque motor (1) alternating torsion and by encoder record torsion angle, with torque sensor (3)
Measure the moment of torsion of anti-fatigue steel cord (9), with the change of pulling force sensor (19) record anti-fatigue steel cord (9) fatigue load
Change, obtain the dynamic Contact loaded between steel wire rope (14) and anti-fatigue steel cord (9) with 2 D force sensor (12)
Load and frictional force；
D () is by changing low-speed high-torque motor (1) torsion angle, the telescopic displacement of servo electric jar A (17) threaded rod
With the folder in frequency, the telescopic displacement of servo electric jar B (10) threaded rod and frequency, loading wire cable clamp (13)
Tool block (26) rotation angle value on fixture rotating disk (25), it is achieved steel wire rope multiaxis fine motion under the conditions of various factors coupling
Fatigue experiment；
G () experiment terminates after, use steel wire rope nondestructive testing instrument that anti-fatigue steel cord (9) fatigue damage is detected.
