TORSION FATIGUE MACHINE

CYCLING TORSION FATIGUE TESTING MACHINE with servo-electric actuator

LiTeM torsion fatigue testing machines run static and cyclic testing on dogbone or spring samples with the most suitable mounting system for the sample in question.

The torsion systems are designed to the client’s specifications, and cover a range of torques from 0Nm to 400Nm. The tests may be run with feedback control of torque or angle. The actuator benches may be configured with vertical or horizontal actuator axes. The torsion meter is mounted on a longitudinal rail to facilitate setting up the test.

The preferred solution has the actuator directly coupled to the sample (direct drive), which is ideal for fatigue testing with very high numbers of cycles and high load application frequency, since the inertia of moving parts is minimized and backlash is effectively eliminated.

When very high torques and dynamic loads are required, the use of torque motors is the key to effective test systems.
