High-frequency fatigue test machine

A novel high-frequency fatigue test machine utilizing a piezo actuator and 4 flexure hinges to generate high-frequency alternating force for fatigue test.

• Capable of high-frequency fatigue test for small scale metal cylindrical/sheet specimen

• Controlled by LabVIEW

• Testing force monitored by a load cell and displayed

• Limiting conditions:

  • Maximum frequency under 1500N
    tensile force: 500Hz

  • Maximum frequency under 500N
    tensile force: 750Hz

  • Regular working condition:
    0N~1500N tensile test at 0Hz~100Hz (without cooling),
    100Hz~400Hz (with cooling)

  • Maximum static tensile force: 2000N

• Compressed air cooling

SEMtester 18240LM Miniature Tensile Stage

• 1000lb load capacity

• Interchangeable load cells

• Adjustable strain rates

• The device is designed to allow tension and compression test

• The stage has been custom designed to perform electrically-assisted (EA) test

Mechanical Testing System

• Non-contact digital image correlation (DIC) method is used for strain measurement

• An infrared camera is used to record the temperature of specimens during EA test
