Series LFV    63 - 600 kN

Advanced high performance solution for Static, Fracture Toughness, LCF, Thermo Mechanical Fatigue (TMF), Fatigue Crack Growth and High Cycle Fatigue Testing.  Servohydraulic Testing Machine in rigid construction with high axial and lateral stiffness, and precision aligned to satisfy a wide range of different  test types.

Multipurpose Dynamic Testing Systems

These machines with its high natural frequency have the actuator integrated in the base of the machine. The alignment fixture is fixed on upper crosshead and provides alignment adjustment of the load string complying with ASTM E1012 and other international standard as required for LCF and other tests. As accessories the alignment verification equipment with stain-gauged specimen (rod), electronic and software is available. This self-supporting unit is optimized for higher frequencies and requires no special foundation. The frame with its movable crosshead by two double acting actuators provides accurate positioning, large and easy accessible test space and allows the integration of fracture toughness bending fixture, environmental or vacuum chamber or high temperature furnace.

Features

  • High stiffness construction, precision aligned
  • Movable upper crosshead for facilitate quick, easy, and accurate positioning by two long-stroke actuators
  • Passive clamping system
  • Inductive hardened, grounded and chromium plated column
  • Double ended, equal area linear actuator with hydrostatic bearings for the best friction free static and dynamic performance, allows high side-loads and emergency running, integrated in machine’s base to shorten the force train.
  • Integrated LVDT displacement transducer
  • Servovalve with manifold mounted direct on the actuator for the highest possible response and most accurate test control
  • Close coupled accumulators to minimize hydraulic pressure fluctuations and filter is mounted direct at the actuator
  • High precision fatigue rated flat load cell for static and fatigue tests fixed on upper crosshead
