AbstractThis study includes device design and design for determining the performance of rigid round thin wires under a bending rotating fatig load over a given lifetime. Small diameter wires are thin wires with a diameter equal to or greater than 1.60 mm (0.63 inch). Bending rotating fatig tester ensures that the wire is rotated at constant speed and subjected to constant amplitude bending deformation. For this purpose, the wire retaining pliers are parallel to each other and the wire between the pliers is 180° paralel. After the speed is entered to the driver, the AC motor power is started by means of the belt-pulley and then transferred to the gears with the help of the cardan shaft. The number of cycles is transmitted to the counter by the encoder and recorded. The number of cycles can be generated in response to the bending deformation applied. The test device was reproducible and healthy.
