Many different structures are tested in laboratory environments to replicate the operational or field environment. Structures subjected to vibration environments are typically affixed to an electrodynamic shaker table via a test fixture. The fixture with the shaker table system provides the boundary condition and dynamic impedance to the structure under test. Because the shaker system coupled with the test fixture defines the impedance to the structure under test, it is important to be able to model the shaker table system. This is a difficult task due to the complicated interface between the shaker table, oil film, bearings, and seismic mass on which the table rests. This paper uses optimization analysis with a modal projection error objective function to develop a representative shaker table model. This technique uses data to update and provide confidence in the realization of the shaker table model.
