1.test properties of anti-fatigue crack, test KIC value,S-N curve
PLG series Computer Control Resonant High Frequency Fatigue Testing
Electromagnetic resonanceHigh-frequency fatigue testing machinehas simple structure, convenient operation, high efficiency, low
energy consumption and other characteristics, therefore it widely
is used in the field of military scientific research, colleges and
universities and industrial production.
High-frequency fatigue testing machine is widely used for testing
properties of anti-fatigue crack, testing KIC value, S-N curve and
so on; it is used for testing fatigue lifetime of all kinds of
parts (e.g. plate gear, crank, bolt, chain, connecting rod, compact
tension and so on) with various fixtures. It may complete the
symmetrical fatigue test, the asymmetrical fatigue test, the
unidirectional pulsation fatigue test, the block spectrum fatigue
test, the modulation fatigue test, the fatigue test at high and low
temperature, three point bending, four point bending, torsion
fatigue tests and so on. At present colleges and universities,
research department and industrial and mining enterprises use the
high frequency testing machine to carry on fracture toughness test
and testing metallic material crack growth rate and limited value
of martial. With the development of microelectronic technology and
computer technology, as well as perfect test method, its use
function is increasing expansion.
This machine undergoes 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

- Base on Windows platform.
- 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
- 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.
- 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
- Control and dynamic force are strict synchronization, which enables
the system to work throughout on the resonance point. The waveform
degree of distortion is small, and the work is stable. It cannot
stop vibration in the high temperature fatigue test and crack
growth rate test
