Resonant Fatigue Testing Machine VIBRRO-FORTE is the latest development in the world of Fatigue Testing. The design of the Vibro-Forte Resonant Fatigue Testing Machine - High Capacity Fatigue Tester is based on a strict further development of the resonant system MAGNODYN. An ideal solution has be found to test long shape components like fasteners, reinforcement steel bars, etc. and round and flat specimens. The changeable frequency range is between 50 and 160 Hz depending on the stiffness of the specimen. Noteworthy is the low weight of a testing machine at this high capacity.
Resonant Fatigue Tester Machines are very often used for fatigue tests (S/N - curves) or in the fracture mechanics for pre cracking and crack propagation tests. This principle has many advantages compared to servo-hydraulic machines.
All types of tests with a Mid number of load cycles are beneficial applications for resonant testing machines because of the Mid testing frequency and as a result very short testing time as well as very low power consumption.
The additional advantage in comparison to servo-hydraulic systems with its actuators, valves and pumps is that maintenance is not required due to the wear-resisting construction.
