Abstract
The dynamic characterization of shakers as well their dynamic interaction with adapters and test fixture are fundamental to understand the response of an unit under environmental testing (random vibration, SRS shock, sine sweep). Numerical modeling of these systems provides support for their design and a good insight how the systems may respond during test. Critical inputs to achieve reliable predictive simulations require accurate input environments, coupling behavior, and test article definition. In this paper experimental methods such as modal analysis, operational deflection shape were used to characterize the dynamic behavior for a variety of vibration test setups, to define realistic input and model validation for the numerical simulation.
