Short Description

INOVA Torsion - Axial Test Bench


  • Equipment/ technical data
    • Tension:  
      • Max. Load  ±40 kN
      • Max. Displacement  ±50 mm
    • Torsion:
      • Max. Torsion: ±8,0 kNm (static), ±6,4 kNm (dynamic
      • Rotation angle: ±50 mm
    • Test - frequency : f ≤ 50 Hz
    • Individual phase at constant frequency possible
    • Clamping tools:
      • Wedge grips for shaft diameters of: Ø 40mm, 50mm, 70 mm
      • Pitch circle diameters (e.g. Ø 140mm / 200mm / 300mm)
      • General clamping length ca. 1250 mm
      • Additional measuring: 3 strain channels
      • Monitoring rate up to 10 kHz
  • Methods
    • Material and component testing with combined torsional-axial-loads
    • Testing of join patches, components, materials, etc.
    • Usage of hydrostatical, gimbal-mounted joints to compensate an offset of the testing sample, for example: e.g. warpage through welding
    • Decoupling of axial and torsional stress
