An aerospace component manufacturer needed an automated test system for a gear box it manufactured for U.S. military applications to certify correct operation under extreme load.
SIS designed and built a test stand capable of generating up to 100,000 in-lbs of torque, with a tightly controlled load tolerance. The stand incorporates a servo motor and massive gear box to generate the torque applied to the output of the gear box, with a 2nd motor under VFD control to drive the gear box input shaft. LabVIEW™ software controls the load system, and records input and output torques for performance analysis. Test results are stored and automatically printed for operational compliance records.
