Product catalog summary
Overview
The ZwickRoell Vibrophore 250 is a high-frequency pulsator that combines dynamic and static material testing capabilities. It is designed for fatigue testing, including tensile, compression, pulsating, and alternating loads, and is suitable for various environmental conditions.

Applications
The Vibrophore 250 is used for quasi-static tensile and compression tests, fatigue strength determination, and fracture mechanics investigations. It is applicable to components like connecting rods, crankshafts, chains, and threaded connectors.

Advantages and Features
  • Combines static and dynamic testing in one machine.
  • High test frequencies for efficient testing.
  • Low energy consumption compared to servo-hydraulic machines.
  • Easy installation and maintenance-free operation.
  • Remote control with color display for ease of use.

Vibrophore 250-1

Product Information ZwickRoell Vibrophore 250 Range of applications The ZwickRoell Vibrophore represents the latest genera‐ tion of high-frequency pulsators, combining for the first time an electro-magnetically excited dynamic testing machine with a fully functional static materials testing machine. This is made possible by the 'two in one' function developed by ZwickRoell. Advantages and features • fully functional static and dynamic testing machine with stiff four-column load frame • high test-frequencies, giving short test times and high specimen throughput • easy to operate via testXpert III and testXpert Research test programs matched exactly to the testing situations • resonance drive has very low energy consumption (only around 2% of that of servo-hydraulic testing machines) • easy to install - no ancillary units or systems (e.g. hydraulics, coolant) needed • maintenance-free system - wear-free components • clamping table at convenient working height for oper‐ ator-friendly testing • remote control with color display showing measure‐ ment channels, machine and test status; also used for machine set-up • testControl II digital measurement and control elec‐ tronics with 10kHz control frequency and 24-bit reso‐ lution • continuously controlled servo motor for fast, accurate mean force control • pulse-width modulation for high control stability and low failure liability • easy test-frequency change simply by varying weights. • large range of standard tools and fixtures As well as being employed for quasi-static tensile and compression tests, Vibrophores are used in particular for determination of fatigue strength with regard to fatigue life and fatigue limit. This allows highly efficient fatigue testing, for example to DIN 50100 (S-N curve), with tensile, compression, pulsating and alternating loads. Other typical applications include fatigue tests on components (e.g. connecting rods, crankshafts, chains and threaded connectors) and standard metal speci‐ mens, together with fracture mechanics investigations on CT and SEB specimens, All tests can be force, displacement or strain-controlled, while with the addition of appropriate devices testing can also be carried out under various environmental conditions (e.g. temperature, aggressive media), toget
