Zwick Vibrophores For Testing Material and Component Durability

Vibrophores are used for determining component and material durability with respect to fatigue life and fatigue limit, for example via fatigue testing to DIN 50100 (S-N curve) under tensile, compression, pulsating and alternating loads.

Typical applications are fracture mechanics tests on CT and SEB specimens, pre-cracking specimens, fatigue and durability tests on components such as screws/bolts and springs, and production and quality control of components exposed to dynamic loads during their working lives.

Key Features

The key features of Zwick vibrophores are:

High testing frequencies (up to 300Hz) ensure short test times, giving high specimen throughput.

Vibrophores operate in resonance frequency. Inherent superelevation of the resonant cycle produces high load and displacement amplitudes at low energy input (around 2% of the energy consumption of servo-hydraulic testing machines).

testXpert^® II(testing software) 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 power-packs or cooling units.

Wear-free components ensure maintenance-free operation.
