The project addresses the design principles and performs finite element analysis (FEA) of vibration fixtures used for testing of space payloads at MIT Lincoln Laboratory. A review of standards that govern vibration testing of space and general payloads is presented. A set of principles and a tutorial for the design of vibration test fixtures is presented. The validation of the design principles is achieved through FEA of a vibration test fixture that involves a structure with panels, rails and support blocks. The FEA code PATRAN/NASTRAN is used and analysis of the three-dimensional computational results leads to design modifications that involve an added third panel. The redesigned fixture has increased stiffness, as well as reduced stress and displacement of its rails.
