Servo-hydraulic fatigue test machine
5 - 25kN bench top system



10kN servo-hydraulic test machine with ±50mm stroke actuator


Frame

  • Rated up to 25 kN tension & compression.
  • Fixed bottom crosshead.
  • Movable top crosshead clamped by pinch bolts.
  • Actuator mounted on top cross head.
  • Two chromed solid steel columns.
  • Top and bottom crosshead and feet powder-coated (RAL7035)
  • Space between columns: 405mm
  • Standard column length: 1200mm.(650mm maximum daylight space).
  • Different column lengths available on request.
  • Weight, including actuator: 275kg


Actuator

  • Mounted on crosshead.
  • Capacity options.
    • 2kN
    • 5kN
    • 10kN
      (Actuators dynamically rated for 210 bar supply
      allowing a delta p = 70 across the servo valve.
      Static = dynamic x 1.5).
    • Built-in excluder seals and dribble lines.
  • Standard stroke options:
    • 25mm
    • 50mm
    • 100mm


Servo valve

  • Standard servo valve for testing frequencies up to 75Hz.
  • High response servo valve for testing frequencies up to 100Hz
    (providing an adequate oil supply is ensured).


Load cell

  • Fatigue-rated in line with the specified actuator.
  • Can be fitted to the piston rod end or bottom crosshead.


Displacement measurement

  • The actuator has an intergral displacement transducer working directly on the rear end of the actuator rod.


Controller


Controller options:
  • Digital controller based on an embedded RISC processor with a PC with Windows-based software as user interface.
  • Analogue controller which may be interfaced with PC for data logging and/or control.


Hydraulic supply


Options
  • Frame may be used with a suitable existing hydraulic supply.
  • Frame may be purchased with a Si-Plan hydraulic power pack.


Accessories


Accessory options
  • Extensometer.
  • Clip gauge.
  • Furnace.
  • Grips
    • Ball nut & ball cup.
    • Plate.
    • Wood's metal pot.
  • 400mm2 slotted tooling plate to suit M12 T-nuts.
'T' slotted tooling place illustrated with load cell mounted on the actautor piston.
