About the system

The servo-hydraulic torsional fatigue bench tests half-shafts, propshafts, clutches, torque converters and housings under repeated torsional load with a rotary actuator. It runs in torque or angle control, with frequencies up to 20 Hz and mounting at joint angles. The heavy-duty version applies ±500 kNm dynamic torque on specimens up to 10 m long.

Technical scope
