Abstract: Vibration qualification testing is an important and common requirement in many industries. In-lab testing is intended to evaluate a component's life expectancy by exposing it to a dynamic environment similar to what it may experience in its field condition. To successfully perform these tests, it is imperative that the component of interest's field boundary conditions (BCs) are replicated as closely as possible in the lab. One approach to achieving accurate dynamic environment testing is to design a fixture that sufficiently represents the impedance of the next-structure (field structure). The process to design and analyze dynamic environment test fixtures (PDADyE) is a method created to guide users through the process of successfully developing a vibration test fixture that accurately reproduces components field BCs. These BCs can consist of multiple directions of excitation and attachment locations between the device under test and its field structure. Using lumped parameter models built in MATLAB, this work demonstrates the process procedure and its effectiveness. [ABSTRACT FROM AUTHOR]
