Short Description

Electromagnetic resonance pulsator (40 – 260 Hz) - Rumul Testronic


  • Equipment/ technical data
    • Testing frequency: approx. 40 – 260 Hz
    • Testing force: ±100 kN (static), ±50 kN (dynamic)
    • Dynamic displacement: ≤ ±2 mm
    • Temperature range: RT ≤ T ≤ 900 °C
    • Positioning of the load cell: top or bottom side
    • Clamping tools:
      • Hydraulic clamping tools for flat specimens 0 mm ≤ s ≤ 20 mm, jaw width: 60mm
      • CT-specimens
      • Wires (Ø 4mm)
      • Four-point bending up to 100 Nm
      • Three-point bending, flat and shouldered round specimens
      • special components
  • Methods
    • Cyclic strength test including determining of cyclic material parameters
    • Testing of cyclic charged components under operational conditions (temperature, lubrication, etc.)
    • Testing programs: e.g. Wöhler fatigue test, crack growth rate testing following ASTM E647, bloc-program testing, pre-cracking of specimens for determination of fracture toughness following ASTM E 399
