Overview

The electronic fatigue testing machine is mainly used for dynamic and static testing and fatigue resistance performance tests of biological materials, elastic bodies, small specimens, etc. It is a single-axis axial loading testing machine, adopting a servo actuator as the control core, forming an automatic control system together with the controller. The control modes include force control, displacement control and strain control. It features low-cycle fatigue test function, low noise, and the loading waveform can cover sine wave, triangular wave, ramp wave, square wave and externally input waveforms. This equipment has low energy consumption, no need for hydraulic oil, cooling water or gas, small footprint and simple operation. It is widely used to test tiny metal specimens, non-metallic materials and parts, elastic bodies for tensile fatigue, compression fatigue, three-point bending fatigue and static performance tests, such as pipe welds, connectors, fasteners, bars, sheets, fiber strips, etc. The microcomputer control can automatically complete the whole cyclic test process of the specimen, and the test report can be printed. Users can adjust the test program according to actual needs during operation. It is convenient to operate and can replace imported products of the same type. It is the preferred choice for universities, scientific research institutes, manufacturing enterprises, aerospace, quality inspection institutions and other manufacturers and users.

Fatigue Performance Testing of Material Specimens

(1) Fatigue control mode 1: Deformation-controlled fatigue test, with force-time curve, deformation amplitude-cycle curve and sine wave curve. (2) Fatigue control mode 2: Force-controlled fatigue test, with deformation-time curve, force amplitude-cycle curve and sine wave curve. 

(3) The software supports a test frequency of 0.01~20Hz. The actual frequency varies with the deformation of the specimen; generally, the frequency will decrease when the deformation is large. 

(4) Judge whether the material specimen is qualified by detecting the service times or force attenuation degree of the test specimen.
