Dynamic Torsional Rigidity Test Frame

Fatigue testing of drive shafts under hydraulic servo control of angle or torque. Torque measured at the static end to avoid wires fatiguing. The prime mover is a semi-rotory hydraulic actuator.

• Determine dynamic stiffness constant
• Short term fatigue capability
• Torque ±100Nm
• Frequencies up to 40Hz at angular deflections of ±30° for short durations
• 12l/min sled powerpack
