Method to Eliminate Unwanted High Frequency Signals above 2 KHz from Accelerometers

Using predictive tools developed in previous work, Dominca will design, build, and test layered-media filters to reduce the transmission of 2 kHz and higher frequencies into accelerometers that are used in explosive and impact events. The size of these external filters will be kept small by incorporating low-wave speed materials and viscoelastic materials. We will use impact testing in our facility to demonstrate the feasibility of the filters. Relying on theory to design the filters, we are largely able to avoid trial and error.
