    Descripersion:

     

    Ultrasonic virbrate 20000 time in 1 second, for some aerospace material , it need fatigue test at million times, if test it by human, it needs about 20years. but by ultrasonic, it need only minutes. By our special desgin ,the output of the horn will be enlarge times, so the strength will not less than the human test too.

    Ultrasonic fatigue strength test, where it had been difImplements materials fatigue testing at 20 kHz. Consequently, it is possible to evaluate ficult to obtain data before. Also, data for 107 cycles can be obtained in about ten minutes.

    The strength reliability of engineering structural materials employed in aerospace and nuclear industrial applications after exposing in service for more than 10 years or more has been questioned, because the traditional fatigue limits that were obtained under fatigue tests up to 10' cycles are difficult to be ever used as criteria for the strength design of these materials. Therefore, the fatigue properties of materials in the life range beyond lo7 cycles are of much interests to machine designers and material engineers. However, investigation of fatigue properties at high cycle regime is extremely time consuming by using conventional fatigue testing method. In this case, ultrasonic testing method may be an effective choice for the possibility of time saving at ultrasonic frequency. Nevertheless, ultrasonic testing method can also be used to investigate the effect of frequency on high cycle fatigue properties, which is of great significance to the design and maintenance of machines and components operating at high speeds, such as jet engines and gas turbine engines. Unfortunately, information on ultrasonic fatigue of metals is far from abundance in contrast to the data available for conventional fatigue of metals and the nature of ultrasonic fracture has not been well understood. For example, frequency effect was reported in some metals and various interpretations such as internal friction and damping properties of materials as well as the slip-band formation were supposed reonsible.[ However, an adequate theoretical explanation is not yet available because fatigue is a much complicated phenomenon and is easily influenced by both material and environmental factors.

     

     

    Test frequency

    20 kHz ±500 Hz (recommended test range 20 kHz ±30 KHz) * The test frequency is determined by the resonance

    frequency of the specimen.

    Horn end face amplitude ±10 to ±50 µm
    Test stress range

    Stress when the specimen undergoes ±10 to ±50 µm

    displacement *The stress value depends on the specimen

    shape and physical properties.

    Power requirements 200 V 3-phase: 2 kVA (air compressor)
    200 V 1-phase: 3.5 kVA (ultrasonic fatigue testing system)
    100 V 1-phase: 1 kVA (including PC, displacement recorder, air drier)

     

     

    Features

    • Accelerated evaluation of the fatigue life of metals and materials is possible at 20 kHz cycle speed. Even 1010 cycle tests are completed in a mere six days.
    • Significant stress can be produced by testing under resonance conditions, and furthermore is economical.
    • Constant stress amplitude control is possible via the controller (provided) with the PC.
    • Optimal for long-life evaluation of materials and high-speed vibration replication experiments.
    • The test system is extremely compact, allowing it to be installed anywhere.
    • The Windows software provided can be used for easy testing from design of resonance specimens through to actual testing.

     

     

     

    Application:

    Fatigue strength of Inconel 718 up to lo9 cycles was enhanced under ultrasonic frequency
    fatigue.
    The initiation and early propagation of small cracks in the surface length range of -30-50
    pm were considerably delayed under ultrasonic frequency fatigue, which contributes mainly
    to the strength enhancement of the alloy.
    Intense transgranular slip bands mixed with intergranularly fractured slants, implying
    that the nature of fracture is brittle-dominated, mark the fracture surface of ultrasonically
    fatigued specimens indicating that the fracture mechanism in ultrasonic fatigue is
    apparently different from that in conventional frequency fatigue.
