The resonance testing system for static and dynamic tests
A vibrophore is a resonance testing machine that uses a mechanical resonator in connection with an electromagnetic drive. The dynamic load is generated by an oscillation system that works when the system operates at full resonance. The mean force is applied by moving the upper crosshead with the lead screw drive.
In the past, resonance testing systems and resonance testing machines were limited to dynamic materials testing (i.e. the determination of fatigue strength). With the newest generation of the vibrophore series high-frequency pulsators, you can perform static tests at test forces up to 1,000 kN. The electromagnetic drive of a vibrophore delivers large force amplitudes with low energy input, so they work more efficiently than conventional instruments.
Typical applications for resonance testing systems are material fatigue tests and durability tests on standardized specimens and components (for example, piston rods, crankshafts, and screws), and production and quality control of components exposed to dynamic loads during their service life, such as concrete and reinforcing steel, as well as quasi-static tensile and compression tests and fracture mechanics tests on CT and SEB specimens.

FAQ
A vibrophore is an oscillation system that uses a mechanical resonator in connection with an electromagnetic drive. Vibrophores can be used to apply a dynamic load on material specimens.
Vibrophores are used for high cycle fatigue tests in the areas of tensile, compression, pulsating and alternating loads. In addition, fracture mechanics tests are performed on CT (compact tension) and SEB (singe edge bending) specimens.
Vibrophores are used on drive chains, crankshafts, piston rods and timing chains in vehicle motors, on turbine blades or concrete and reinforcing steel.
ZwickRoell vibrophores are available in eight models for resonance fatigue tests up to 1,000 kN. The extremely stiff load frame consists of four columns to achieve excellence in guide qualities. Mechanical clamping of the oscillating crosshead and the implementation of the testXpert III testing software transform the Vibrophore into a true static materials testing machine.
