The goal is to develop external mechanical filters to eliminate signals above 2 kHz from accelerometers. Domincas patented layered-media approach will be used to develop filters for high-shock accelerometers used in explosive and impact events. Layered-media theory has been applied successfully in optical thin films, acoustics, and signal transmissions. Filters with and without viscoelastic materials will be developed. Viscoelastic materials will damp resonance of the filter/accelerometer combination. We combine theoretical, computational, and experimental methods. We will improve our predictive tools to incorporate temperature- and frequency-dependent viscoelasticity. Prototypes will be developed for accelerometers that our Navy client currently uses frequently. They will be tested in our laboratory to compare to predictions, and to demonstrate feasibility. Promising prototypes will be tested in the field in collaboration with our Navy client.
