Application:

HLG Series Electromagnetic Resonance Fatigue Testing Machine is used for fatigue tests on metallic materials and components under tension, compression or reversal load. Equipped with relevant grips, three-point bending test, four-point bending test, tension and compression of sheet sample test, tension and compression of circle test, gear wheel, bolt, connecting rod, roller chain, crackle expanding tests can be done on this machine. The series of testing machines undergo optimization design, the structure is rational. The automatic controlled system adopts the advanced pulse wide control system and new-type power amplifier to improve the reliability of the electric system .

It has high efficiency, easy to shake, no-stop shake, low energy consummation, high controlling accuracy, small fluctuation. The machine is complied with DIN50100.

Software Introduction:

The operation system is under Window XP. The computer will show the load in real time, peak load (Max. & Min.) and the testing curves.

l Over load protection;

l Testing data real-time display: In fatigue testing, it can show testing curves for different time and different specimen. The testing curves can be in planar and three-dimensional.

l Testing data storage and analysis: Testing curve is stored into data base and it is suitable for analysis and management.

Software features:

l Easy to operate, convenience and reliability;

l Display parameters, such as average load, alternating peak load, resonance frequency and cyclic fatigue times in real time.

l Strong and broad test function: routine fatigue test, program control loading test, block spectrum test, alternating load envelop line test (Wave shape is set as sine wave, triangle wave and square wave).

l Multiple test parameters setting mode: can take average load value, alternating peak load value as preset mode, also can take Max. load, stress ratio, Max & Min load as preset mode, and allow apply different load unit.

l Abundant data analysis and procession.

l Automatically store various kinds of test data, print test reports and test curve, complete “S-N curve” data procession and curve drawing, and draw frequency-time curve and load-time curve.

l Safe projective function: overload, over-current, upper and lower limit of the set load protection. Machine stops when test finishes or encounters emergency.
