A new method is proposed for system identification of substructures, such as payloads to be flown aboard the Space Shuttle. In the vibration test, all interface degrees of freedom where the substructure is connected to the carrier structure are either subjected to active excitation or are supported by a test stand with the reaction forces measured. A linear, viscous-damped model is obtained (M, C, and K) with all interface-DOF entries included. Multiple-boundary-condition tests are not required, and test-stand dynamics is accounted for without a separate test-stand modal test or finite element modeling of the test stand.
