PLG High Frequency Fatigue Testing Machine
The Series electromagnetic resonance fatigue testing machines are used for fatigue tests of metal material and component under tension, compression or reversal load .If the relevant grips are provided, three-position bending test ,four-position bending test ,tension and compression of sheet sample test ,tension and compression of circle test ,gear wheel , bolt , connecting rod , roller chain, crackle expanding test are available.
The serial testing machines undergo optimization design and the structure is rational. The automatically controlled system adopts the advanced pulse wide control system and new-type power amplifier to improve the reliability of the electric system .It is with high efficiency, easy to shake, no-stop shake, low energy consummation, high controlling accuracy, small fluctuation. The machines comply with DIN50100.

Easy to operate, convenience and reliability;
Display parameters, such as average load, alternating load peak, resonance frequency and cyclic fatigue times in real time.
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).
Multiple test parameters setting mode: can take average load value, alternating load peak value as preset mode, also can take Max. Load, stress ratio, Max & Min load as preset mode, and allow apply different load unit.
Abundant data analysis and procession
Automatic 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, load-time curve.
Safe projective function: overload, over-current, upper and lower limit of the set load protection. Machine stops when test finish or encounter emergency.
