Aerostructures Axial-Torsional Test Facility
This equipment is a large, multi-axial, servo-hydraulic testing machine purchased in 1988 from the
MTS Systems Corporation (Eden Prairie, Minnesota), and it is located in 107 Hancock Hall. This machine
is capable of simultaneously loading of test articles axially and torsionally, controlling either the
axial load or axial displacement and controlling either torque or rotation. The computer automation
(MTS TestStar workstation and Model 490 Digital controller) makes it possible to specify random
independent biaxial loading on each axis in fatigue, or of a controlled phase relationship between
each axis, or to input load spectrums obtained from field measurements, as well as providing data
acquisition. The load unit has a fatigue load rating of 110,000 lbs axial and 50,000 lbs-in. torsional.
The usable test space is 60 inches vertical spacing between actuator and load cell. Horizontal clearance
between the load frame columns is 30 inches. The maximum stroke of the linear actuator is 6 inches, and
the maximum rotation of the rotary actuator is 100 degrees.
