Abstract

Shock accelerometer internal and mounting dynamics are analyized and the contribution to the sensor output is evaluated. This includes an analysis of uniaxial and triaxial accelerometer cross-talk (cross axis sensitivity effects), the filtering characteristics of polysulfide films, and the influence of triaxial block transient dynamic response on the shock accelerometer output. It is shown that the polysulfide acts as a lowpass filter and dissipates energy in the frequency range of sensor resonance. Features in the data, such as energy spectral density, cross axis sensitivity, and mode shapes of the triaxial block are highlighted.
