Vibrophore®

A Vibrophore is used to determine fatigue strength, with regard to fatigue life and fatigue limit, for example fatigue testing to  DIN 50100 (Wöhler curve) under tensile, compression, pulsating and fatigue loads. Typical applications are fracture mechanics tests on CT and SEB specimens, pre-cracking specimens, fatigue and durability tests on components (e.g. screws and springs), and production and quality control of components exposed to sinusoidal loading during their working lives.

• Vibrophores are available in 5 models with various test loads:
  - 5, 10 kN
  - 20, 30 kN
  - 50, 100, 150, 200, 250 kN
  - 300, 400 kN
  - 500, 550 kN

• High testing frequencies (up to 300 Hz) ensure short test times, giving high specimen throughput.
• Vibrophore operates in resonance frequency. Inherent superelevation of the resonant cycle produces a high load and displacement amplitude at low energy input (around 2% of the energy consumption of servo-hydraulic testing machines).
• testXpert^® test programs precisely tailored to testing requirements make operation very straightforward. 
• Installation is also very easy – the vibrophore requires no additional elements such as hydraulic oil or cooling.
• Wear-free components ensure maintenance-free operation.
