TestWorks Group were commissioned by a major avionics OEM to develop an automated avionics instrument test system which included requirements to rotate the unit-under-test (UUT) in three axes, to simulate pitch, roll and yaw movements. Initially a third-party movement table was considered, but due to specific customer requirements a suitable unit could not be sourced, therefore a custom designed gimbal system and movement table was developed and built in-house. The unit includes a clamping mechanism to accurately locate the UUT in position, automated pushbutton actuators and a camera for additional tests. Careful cable management was required for both the control/positioning cabling and also for connections to the UUT, actuators and camera. The gimbal table is part of a complete functional test system developed and built by TestWorks, with the table being controlled using National Instruments LabVIEW software.
