Can New‑generation Servo Hydraulic Actuator Meet Strict ISO 12106 Low‑cycle Fatigue Requirements?
HST GROUP has unveiled its HST‑8244.XX series servo hydraulic actuator, a high‑performance dynamic‑static loading unit engineered to satisfy ISO 12106, the international standard for metallic axial strain‑controlled low‑cycle fatigue testingISO.
This double‑rod fatigue‑resistant servo hydraulic actuator delivers force capacity ranging from 15 KN to 1000 KN, with piston strokes of ±75 mm, ±100 mm and ±125 mm and maximum usable frequency up to 20 Hz. It integrates MOOG high‑performance servo valves, Interface fatigue‑grade Load Cell and coaxially‑mounted TE LVDT displacement sensor. Dual closed‑loop control for force and displacement enables smooth, disturbance‑free mode switching, which is critical to fulfil ISO 12106’s strain‑controlled Test specificationsEuropean S....
Nitrided piston rod paired with premium German sealing and support components strengthens side‑load resistance and long‑cycle service life. Hydraulic buffer prevents hardware damage in unexpected operation. Universal hinged mounting ears support horizontal, vertical and multi‑orientation installation for diverse test frames.
The matched digital controller offers 10 kHz sampling frequency, supporting sine, triangle, square, trapezoidal and custom waveforms. Supporting software completes high‑/low‑cycle fatigue experiments, real‑time curve plotting and automated data processing. The full‑set solution helps laboratories generate repeatable test data conforming to ISO 12106 and accelerates material‑product R&D cycles.
