DEVELOPMENT OF OWN DEVICES FOR GIGACYCLE FATIGUE TESTS OF MATERIALS

  • Equipment for fully reverse tension-compression cycle loading.
  • The device allows loading with or without static pre-stress.
  • The operating frequency of 20,000 ± 500 Hz allows to achieve 10 million cycles in 8 minutes and 10 billion cycles in less than 6 days.
  • Ultrasonic generator with the possibility of controlling the output amplitude of the signal.
  • Horizontal configuration of the converter-booster-sonotrode-sample chain.
  • Continuous control of the output amplitude of vibrations.
  • A wide range of output amplitudes of vibrations is covered by sets of used boosters and sonotrodes.
  • Air cooling of the ultrasonic converter.
  • Cooling of material samples with air or water.
  • Efficient cooling by the closed water-cooling circuit.
  • Optional induction heating for tests at high temperatures (up to 800 °C).
  • The device can be modified according to the customer’s wishes.
  • ULTRATECH s.r.o. takes care of sales, distribution and service.
