Satellite hardware subjected to pyroshock events during launch must pass one or more qualification tests to ensure proper function during operation in space. This research involves the dynamic characterization of a resonant plate that is used to perform qualification tests. The goal is to develop an analytical model that accurately predicts the shock response spectra (SRS) for a variety of configurations of the resonate plate. Experimental shock data is collected to analyze the system’s variability. Experimental modal tests are performed to determine the system’s mode shapes, natural frequencies, and damping. A finite element model is constructed to predict higher frequency mode shapes for use in the analytical model. The modal superposition technique is then employed to solve for acceleration time responses at specific locations on the plate which allow for the calculation of SRS at each point. The paper concludes by discussing multiple case studies that analyze the effects of key parameters on the analytical model’s predicted SRS. |
