Abstract
Using computer generated “ramp burst” pulses on a single axis thruster, a “performance map” for a ball and tube type crash sensor is developed which indicates the performance sensitivity to cross-axis vibrations. The arming (safing) sensor reviewed here exhibits a cross-axis sensitivity to frequencies in the range of 200-400 Hz. With this data is it possible to optimize the sensor bracket design or the sensor/vehicle interface designs such that the system resonance can be maintained above 400 Hz, thus minimizing the cross- axis effects.
