1000kN capacity testing machine
04 November 2013
With energy consumption that is said to be about 2% of that of a servo-hydraulic testing machine, Vibrophores represent a cost-effective solution to determining the fatigue strength of components and materials. Zwick now offers a high frequency pulsator with electromagnetic drive up to 1000kN – the Vibrophore 1000.
Durability is determined in the fatigue test to DIN 50100 (S-N curve) in the tensile, compression, pulsating and alternating load ranges. Typical application are fatigue tests on materials and components (e.g. bolts/screws, chains, connecting rods and reinforcing steel), as well as production control and quality control of components which are subjected to dynamic loads during their lifetimes.
Added to this are fracture mechanics investigations on CT (Compact Tension) and SEB (Single Edge Bending) specimens, together with tests in an extended temperature range and in liquid media, as well as dynamic torsion and flexure tests.
Zwick Vibrophores are available with forces ranging from 5 to 1000kN. In addition to increased capacity, the key feature of the Vibrophore 1000 is the load-frame concept. The extremely stiff load frame consists of 4 columns, giving it excellent alignment properties. The controlled mean force is applied via two lead-screws, while a separately controlled electromagnetic drive applies the dynamic load to the specimen.
