These test rigs consist of two torque motors arranged face-to-face (4-quadrants operation) and intended to apply medium to high torques either at low spinning speed or under fully Fatigue conditions (non-spinning).
Besides conventional sine signals and plateau type multi-block programs, high-dynamic real-time –road profile– torsion impact signals can be reproduced. For instance, following tests can be conducted on sideshafts:
- High torque – high angle at low speed
- Pull-out (dynamic self-disassembly)
- Torsional Impact
- Dual-specimen torsional Fatigue (two specimens tested simultaneously – like two independent Fatigue test rigs)
Performance of these test rigs for standard configurations:
- Torques up to 11000 Nm
- Spinning speeds up to 600 rpm when used as Quasi-static
- Sine frequencies up to 10 Hz when working as Fatigue
- Angular velocities up to 3600 deg/s
