ZwickRoell LP Vibrophores

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.
