Characterization of accelerometer mountings in shock environments
This report describes the shock test characterization of four accelerometer mounting techniques which are: adiprene and wax, polysulfide rubber and wax, restrained adiprene, and hard mount. The mountings have all been used in field tests, and the shock testing provides some simulation of the field test environments. The characteristics of these mountings are analyzed in the time-domain and in the frequency-domain and are compared to the response of a reference accelerometer at two different shock levels, approximately 2 kg and 7 kg. While soft mounting techniques can be used to guarantee accelerometer survival in severe mechanical environments, this report documents the tested mounting materials to be highly nonlinear. These nonlinearities result in signifcant data distortion at frequencies above a few hundred hertz.
