Servo-pneumatic fatigue test machine
2 - 10kN bench top system



5kN servo-pneumatic test machine configured to test a prosthetic lower limb 5kN servo-pneumatic test machine configured to test a prosthetic lower limb

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: 220kg

Actuator

  • Low friction grade pneumatic actuator.
  • Mounted on crosshead.
  • Capacity options (shown as the static rating for 7 bar air supply):
    • 2kN
    • 5kN
    • 10kN
    • 15kN
    • 20kN
    • 25kN
  • Standard stroke options:
    • 50mm
    • 100mm

Load cell

  • The fatigue-rated load cell can be mounted on either the top or bottom crosshead.

Controller

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

Pneumatic supply


The compressed air supply for the actuator should be:
  • Between 5 and 10 bar.
  • Clean.
  • Dry.
  • At room temperature.
  • Free of oil contamination.
  • Filtered to 5 micron maximum particle size.

Advantages of pneumatic

  • High reliability - low maintenance.
  • Major price advantage over servo-hydraulic and screw-thread machines.
  • Little or no heat generated.
  • No fire risk.
  • Runs from filtered workshop air or bottled air.
  • Low inertia.
  • Inherent predictable stall thrusts.

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.
