Book excerpt: An analytical investigation was performed to study the dynamic response to impact loadings of acceleration sensors having various mounting characteristics. Analytically represented impacting bodies were subjected to input force pulses of half-sine, triangular, quarter -sine, and rectangular shapes, approximating typical target impact acceleration signatures. Studies were made with an analog computer of the acceleration time histories measured by acceleration sensors of different mass which are coupled to the impacting body by a mounting system having various combinations of damping and spring stiffness. Boundaries for the system parameters were established that defined conditions for which the accelerometer assembly and its coupling have a negligible effect on the accelerations experienced by the impacting body. These boundaries define ranges of the parameters of the two-degree-of-freedom system for which the impact response characteristics can be evaluated from a single-degree-of- freedom analysis. Ekirther, with a knowledge of these parameters and the impact velocity, the shape and the magnitude of specific input pulses applied to the impacting body can be defined from characteristics of the acceleration-time- history response of an acceleration sensor mounted to that body.
