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
