Abstract
A support system for ground vibration testing of a large flexible structure. The system includes a plurality of light weight lifting mechanisms that impart an upward force sufficient to lift the flexible structure off the ground. The system also includes a plurality of lift beams coupled to the lifting mechanisms in a pendulous manner. Each lift beam attaches to the flexible structure at one of a plurality of designated jack points, and lifts the flexible structure off the ground when the upward force is imparted by the lifting mechanisms. Thus, the flexible structure is thereby pendulously suspending above the ground such that rigid body mode test data is decoupled from first flexible mode test data.
