USF-2000A — Ultrasonic Fatigue Tester

This unique instrument based on ultrasonic resonance allows:

– 10⁹ cycle testing in 14 hours (compared to 39 days at 300Hz)
– 10¹⁰ cycle testing in 6 days (compared to 365 days at 300Hz) 

Features

• 20kHz ± 500kHz test frequency
     10⁹ cycle tests in 14 hours (39 days at 300Hz)
     10¹⁰ cycle tests in 6 days (365 days at 300Hz)
• Stress Range: 100MPa to 1,200MPa
     1000MPa steels may be tested
• ±50 µm displacement at end surface of horn
• Recreates fatigue failure appearance from micro-defects and inclusions.
• Resonance technique reduces power consumption compared to traditional fatigue tests.
• Small tabletop design 
• Air-cooled, no oil or cooling water required. 
• Mean stress load option is available.

Configuration

Standard Components

1. Very high cycle resonance system
   – Main unit
   – Control box
   – Power supply
   – Piezo actuator
   – Horn
   – Air dryer
2. PC System
3. Very high cycle fatigue test control measurement software

Air compressor, non-contact displacement sensor, displacement calibrator and displacement recorder are also required.
