This series of testing machines is a special testing equipment for fatigue life testing of parts and components, designed and manufactured in strict accordance with national standards. It is widely used in tensile and compressive fatigue performance testing of various metal and non-metallic material samples such as pipe welding parts, connectors, and parts. The entire cycle test process of the sample is automatically completed by a microcomputer, and the test report can be printed out. Users can adjust the test program according to actual needs during use, and the operation is extremely convenient. It can replace imported products of the same type and is the first choice for manufacturers and users such as colleges and universities, scientific research institutions, machinery manufacturing, aerospace, and quality inspection agencies.
GA-W50 High Frequency Universal Plastic Rubber Alloy Steel Metal Fatigue Tester Testing Machine Device Equipment Equipment composition and function introduction
1. Portal movable loading platform
Two-column portal design, cross structure of upper beam, manual locking adjustment, four anti-vibration foot cups installed at the lower end, large diameter column structure frame, high strength.
2. Servo actuator, drive device (single channel) The effective stroke of the actuator is ±50mm, equipped with a high-precision digital displacement sensor, and a buffer zone is designed at the limit position of the actuator amplitude to avoid damage caused by uncontrolled operation.
The actuation system adopts an anti-backlash device, automatic centering of the force value, reducing lateral force, reducing the impact during high-frequency tension and compression tests, and effectively improving the test waveform.
3. Data acquisition and control system ,It consists of a single-channel fully digital dynamic and static servo controller, computer and software, and accessories.
4. High-precision load sensor
Adopt a high-precision load sensor with an overload capacity of 120%. Place it at the front end of the actuator or on the work surface, and the sensor is calibrated before leaving the factory.
GA-W50 High Frequency Universal Plastic Rubber Alloy Steel Metal Fatigue Tester Testing Machine Device Equipment Equipment Function
Fatigue performance test of material samples
(1) Fatigue control mode 1: fixed deformation fatigue test, force-time curve, deformation amplitude-frequency curve, sine wave curve
(2) Fatigue control mode 2: fixed force fatigue test, deformation-time curve, force amplitude-frequency curve, sine wave curve
(3) The software supports 10Hz test frequency. The actual frequency varies according to the deformation of the sample. Generally, when the deformation is large, the frequency will decrease!
(4) Determine whether the material sample is qualified by detecting the number of times the material sample is used or the degree of force attenuation.
(5) During the test, if the sample is damaged or the force attenuates to the set value, the machine can automatically stop. If it is not completed on the first day, it can be continued on the second day, and so on.
