USF-2000

Ultrasonic Fatigue Testing System

With the ultrasonic fatigue testing system USF-2000A in standard- or mean stress configuration fatigue tests in the Very-High-Cycle-Fatigue (VHCF) range can be performed time- and cost-efficiently with the frequency 20 kHz. Results about the fatigue behaviour and the fatigue strength at 107 cycles will be available after ca. 10 minutes and at 1010 cycles after ca. 6 days.

 

[Features]

  • Economic determination of the fatigue behaviour and the fatigue strength, i.e. usage for variety inspection in research and development or quality control in mass production
  • Accelerated evaluation of the performance capability at 20 kHz, even tests until 1010 cycles are completed after ca. 6 days
  • High-precision stress- and amplitude control for excellent result quality  
  • Windows software package includes all necessary actions from specimen design (without FEM skills) until user-friendly test execution and evaluation
  • Compact system design for various installation possibilities without necessity of a lab infrastructure (cooling water, hydraulic oil etc.)
  • Mean stress loading is available as option: More information
